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
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?
This should be enough information to help you.
