Question

Match the shapes of triangle to the type of triangles.

• A. Acute triangle
• B. Obtuse triangle
• C. Right triangle

Answer 1

Triangles can be classified based on their angles in the following way:

In the first triangle, all angles are less than ${90}^{\circ }$, therefore the triangle is an acute triangle.

In the second triangle, one angles is equal to ${90}^{\circ }$, therefore the triangle is a right triangle.

In the last triangle, one angles is greater than ${90}^{\circ }$, therefore the triangle is an obtuse triangle.
