Assuming only the lengths of the sides of a triangle are given, how can you determine if the triangle has a right angle?

It is possible to determine if a triangle contains a right angle using Pythagoras' theorem . If the squares of the two shorter sides add up to the square of the hypotenuse, the triangle contains a right angle.

The Pythagorean theorem

Step-by-step explanation:

If you have the length of each side of the triangle, you have to apply the theorem. If you get the true statement, you'll know for sure that you have a right triangle.

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
