Question

Match the triangles to their names based on the properties.

• A. Isosceles obtuse
• B. scalene obtuse
• C. isosceles right

Answer 1

The blue-colored triangle has two equal sides and one angle equal to ${90}^{\circ }$, so it is an isosceles right.


The white-colored triangle has three unequal sides and one angle more than ${90}^{\circ }$, so it is a scalene obtuse triangle.


The orange-colored triangle has two equal sides and one angle is greater than $90$ degree, so it is an isosceles obtuse triangle.
