The Final Classification Challenge

Topic:Equilateral Triangles, Isosceles Triangles, Right Triangles, Scalene Triangles, Triangles

You've become an expert at classifying triangles by their sides and by their angles. Now it's time to put it all together! Every triangle actually has two names—one that describes its sides and one that describes its angles. For example, you can have a Right Isosceles triangle or an Obtuse Scalene triangle.Your final mission is to build the following specific types of triangles. This will test all your skills!

Your Challenge List:

An Acute Isosceles triangle
A Right Scalene triangle
Obtuse Isosceles triangle
Any triangle type in the chart below

Drag the vertices A, B, and C until the side and angle measurements match the descriptions above. Good luck!

A triangle has side lengths of 5 cm, 5 cm, and 8 cm. One of its angles is 94°. What is the triangle's full classification?

Select all that apply

A
Acute Scalene
B
Obtuse Equilateral
C
Obtuse Isosceles
D
Right Isosceles

Check my answer (3)

Select all that apply

A
Right Isosceles
B
Acute Isosceles
C
Right Scalene
