Question

Determine if a triangle with the given dimensions is a right triangle. If it is, which angle is the right angle?

A. Yes, angle A is the right angle.
B. Yes, angle B is the right angle.
C. Yes, angle C is the right angle.
D. No, it is not a right triangle.

Answer 1

This triangle is a 30-60-90 triangle, so when drawn, Angle A is the right angle, Angle B is the 30 degrees angle, and Angle C is the 60 degrees angle. So the answer is A.

Answer 2

A. Yes, angle A is the right angle.

Explanation:

Remember a right angle triangle can be solved using the right -angle theorem.

A²= B²+C²

let's observe that AB² + CA² = BC²

i.e ( 5√3)² + 5²= 10²

75 + 25 = 100

Making BC the hypotenuse and the angle facing the hypotenuse is angle a which is a right angle
