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:

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?

This should be enough information to help you.

c. Isosceles and rt.

To determine the correct answer, we need to understand the properties of triangles and their types based on side lengths and angle measures:

1. Scalene Triangle: A triangle with three different side lengths.
2. Isosceles Triangle: A triangle with at least two congruent sides.
3. Equilateral Triangle: A triangle with three congruent sides.
4. Right Triangle: A triangle with one angle measuring 90 degrees.
5. Acute Triangle: A triangle where all three angles measure less than 90 degrees.

Since the given triangle has two congruent sides and two angles measuring 45 degrees, we can conclude that:

a) It cannot be scalene since two sides are congruent.
b) It cannot be equilateral since only two angles are congruent, not all three.
c) It cannot be acute since an angle of 45 degrees is bigger than an acute angle.

Therefore, the correct answer is: b) Isosceles and acute.
