Question

How many right angles do a right triangle have?

Answer 1

Hint: In this question, you were asked to find the numbers of the right angle in a right triangle. The right angle is ${90^ \circ }$. The definition of the right-angle triangle will help you to solve this question. So let us see how we can solve this problem.

Complete Step by Step Solution:
In the given question we have to find the number of right angles in a right triangle. So, a right angle triangle is a triangle that has one right angle and the other two angles are less than ${90^ \circ }$.
Moreover, we know that the sum of the angles of a triangle is ${180^ \circ }$. So if we consider that two angles are of ${90^ \circ }$ each then we would not be able to make the third angle because the sum of those two angles will be ${180^ \circ }$ and the sum of all angles of a triangle is exactly ${180^ \circ }$.

Therefore, there is only one right angle in a right triangle.

Note:
The above question is solved with the definition and an example. We can determine from the name of the right-angle triangle that there is only one right angle. The other two angles of the right triangle are less than ${90^ \circ }$.
