A triangle with two congruent sides and two angles that both mesuare 45 is

a. scalence and right
b. isosceles and acute
c. isosceles and right
d.equilateral and acute

• Math -

Triangles:
no sides the same: scalene
2 sides the same: isosceles
all (3) sides the same: equilateral

Since a triangle's angles must add up to 180, if there are 2 45 degree angles, the one left must 90 degrees. Do you know what a triangle is called if it has a 90 degree angle?
