Question

How would you describe this triangle?

A.
isosceles
B.
equilateral
C.
obtuse
D.
scalene

Answer 1

isosceles = a triangle in which two sides are equal.
equilateral= a triangle in which all three sides are equal
obtuse= a triangle in which an angle is greater than 90°

Answer 2

a) isosceles triangle - a triangle with two sides equal and two angles opposite to the equal sides are equal
b) equilateral triangle- a triangle with all sides equal and all angles are equal to 60°
c) obtuse angle-
An obtuse triangle is one with one obtuse angle and two acute angles. Since a triangle's angles must sum to 180°, no triangle can have more than one obtuse angle. 
scalene triangle- a triangle with all unequal sides but sum of all angles of triangle is 180°
(sum of all angles of triangle is equal to 180° in all types of triangles)
