Question

Study the triangle. What can you conclude about the angle measures? The angle measures are 30°, 60°, and 90°. The angle measures are 45°, 45°, and 90°. The triangle has a 90° angle, but the other angle measures cannot be determined.

Answer 1

Answer:

In the given triangles all the triangles have one angle equals to 90° so, all three triangles are right angled triangle.

Step-by-step explanation:

If a triangle has one angle equals to 90° then that triangle is called right angled triangle.

In the given triangles all the triangles have one angle equals to 90° so, all three triangles are right angled triangle.

1) The angle measures are 30°, 60°, and 90°.

One angle is 90° and is right so the triangle is right angled triangle, the other two angles are 30° and 60°. The sum of all angles is equal to 180°

2)  The angle measures are 45°, 45°, and 90°

This is an isosceles right angled triangle because one angle is 90° and other two angles are same i.e 45°

3) The triangle has a 90° angle, but the other angle measures cannot be determined.

If one angle is 90° then the other two angles will be less than 90°(acute angles) and the sum of all three angles would be equal to 180°

Answer 2

Answer:

A.  The angle measures are 30°, 60°, and 90°.
