Can a triangle have angles 90 degree 90 degree 20 degree Why or why not?
Can a triangle have angles 90 degree 90 degree 20 degree Why or why not?
No a triangle cannot have these angles because all angles sum cannot be greater then or less than 180 degree.
What is the 30 60 90 Triangle rule?
Tips for Remembering the 30-60-90 Rules Remembering the 30-60-90 triangle rules is a matter of remembering the ratio of 1: √3 : 2, and knowing that the shortest side length is always opposite the shortest angle (30°) and the longest side length is always opposite the largest angle (90°).
Can a triangle have more than one 90 degree angle?
Ans- No a triangle cannot have more than one right angle as if there are 2 right angles the their sum will be 180° and the third angle will exceed the sum.
Which triangle has an angle which is 90?
right triangle
Which is the shortest side in right angle triangle?
and the shortest side is opposite the smallest angle. Thus, in a right triangle, the hypotenuse is always the longest side….

| 3π-4π-5π | ( k = π ) |
How do you prove a triangle has a right angle?
Proof of Right Angle Triangle Theorem Theorem:In a triangle, if square of one side is equal to the sum of the squares of the other two sides, then the angle opposite the first side is a right angle. Hence the theorem is proved.
What is the greatest number of right angles in a triangle can contain?
Explanation: A triangle has 180o as the sum of all its internal angles, no more, no less. If one angle is 90o , then you can have two 45o angles, one 30o and a 60o , an 81o and a 9o – pretty much any combination of numbers adding up to 90 to make the total 90+90=180 .
What are the 3 angles of a right triangle?
Right triangles are triangles in which one of the interior angles is 90 degrees, a right angle. Since the three interior angles of a triangle add up to 180 degrees, in a right triangle, since one angle is always 90 degrees, the other two must always add up to 90 degrees (they are complementary).
Does 9 12 and 15 make a right triangle?
The three sides 9 in, 12 in, and 15 in do represent a right triangle. Since the square of the hypotenuse is equal to the sum of the squares of the other two sides, this is a right triangle.
Does 4 5 6 make right triangles?
For a set of three numbers to be pythagorean, the square of the largest number should be equal to sum of the squares of other two. Hence 4 , 5 and 6 are not pythagorean triple.
Does 5 12 and 13 form a right triangle?
Yes, a right triangle can have side lengths 5, 12, and 13. To determine if sides of length 5, 12, and 13 units can make up the sides of a right…
What type of triangle does 5/12 13?
scalene triangle
Does 7/11/13 form a right triangle?
Because the two sides are equal, this is a right triangle. NOTE: All of the lengths in Example 4 represent the lengths of the sides of a triangle. For example, 4, 7 and 13 cannot be the sides of a triangle because \begin{align*}4+7\end{align*} is not greater than 13.
Does 4 8 12 make right triangles?
Answer: No, side lengths of 4, 8, and 12 do not form a right triangle.
Does 20 21 and 29 make a right triangle?
. The right triangle having these side lengths is sometimes called the 3, 4, 5 triangle. One side may have two of these divisors, as in (8, 15, 17), (7, 24, 25), and (20, 21, 29), or even all three, as in (11, 60, 61). …
Does 12/16 20 Make a right triangle?
So we type GCF(12,16,20) and we get 4. And lo and behold, we get a Pythagorean Triple of 3, 4, 5. So yes, this is a right triangle.
Does 15 36 39 form a right triangle?
Example 1: Solve for x. Therefore, the length of the base x of the triangle is approximately 12.1. The Converse of the Pythagorean Theorem states that, if is true, then the given triangle is a right triangle. Hence, the set {15, 36, 39} is a Pythagorean Triple.
Are 8 15 and 17 a Pythagorean triple?
What is a Pythagorean Triple, you ask? It is three numbers that when you add the squares of the two smaller numbers that equals the square of the largest number. And by the way, today is 8/15/17, which is a Pythagorean Triple.
What type of triangle is 15 20 36?
The correct answer for this question is: “Cannot form a triangle. (15+20) is not greater than 36.”
Can a 6 8 10 make a right triangle?
Answer: Yes, a triangle has side lengths 6, 8, 10 is it a right triangle.
Does 10 24 26 form a right triangle?
Answer Expert Verified Yes. For right triangles, the sum of the squares of the shorter sides is equal to the square of the longer side. Thus, this is a right triangle if 10^2+24^2=26^2. Expanding these squares, we have 100+576=676, which is true.
Does 6 8 12 make right triangles?
Is this a right triangle? O A. Yes, because 62 +82 < 122.
What is the longest side of a right triangle called?
hypotenuse
What is the longest line in a triangle?
In geometry, a hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle.
Does Pythagorean theorem only work on right triangles?
Pythagoras’ theorem only works for right-angled triangles, so you can use it to test whether a triangle has a right angle or not.
Where is the angle of depression on a triangle?
The angle of depression is always OUTSIDE the triangle. It is never inside the triangle. It is a downward angle from a horizontal line.
Which angle is the angle of depression?
90°
What is the formula for angle of depression?
The angle of depression may be found by using this formula: tan y = opposite/adjacent. The opposite side in this case is usually the height of the observer or height in terms of location, for example, the height of a plane in the air. The adjacent is usually the horizontal distance between the object and the observer.
Can an angle of depression be more than 90?
An angle of depression can never be more than 90 degrees.
What kind of triangle has a right angle?
A triangle that has three acute angels is called an acute triangle. A triangle that has one right angle is called a right triangle. A triangle that has one obtuse angle is called an obtuse triangle. When a triangle has three congruent sides, we call the triangle an equilateral triangle.
