A triangle with two congruent sides and two angles that both measure 45 is
a.scalene and right
b.isosceles and acute
c.isosceles and right
d. Equilateral and acute
Wow..I gave you plenty of information yesterday to be able to solve this on your own. Go back and read the information I gave you. I could not be any clearer.
Here is the information I gave you yesterday:
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.
c. Isosceles and rt.
