Question

Match the triangles according to their properties.

• A. isosceles acute
• B. scalene obtuse
• C. equilateral acute

Answer 1

In the first triangle we have one angle more than $90$ degrees and all three sides are different. So it it scalene obtuse.

In the second one, we have two equal sides and equal angles which are also less than $90$ degrees. This makes the triangle an isosceles acute triangle.

And finally in the third figure, we have three equal sides and three equal angles, less than $90$ degrees, which means this is an equilateral acute triangle.
