An isosceles triangle is know to be a triangle that has 2 equal sides. Therefore an isosceles triangle has 2 equal sides.

'; explain[1] = '#2

The parts of an isosceles triangle are labeled as follows: a vertex angle (usually displayed as the top most angle), the 2 sides that form the vertex angle are the two equal sides, and the 3rd side is known as the base, the other two angles are known as the base angles.

'; explain[2] = '#3

An isosceles triangle has two equal sides, this creates a triangle that also has 2 equal angles, the equal angles are those that are directly across from the equal sides

'; explain[3] = '#4

An equalateral triangle is known to be a triangle that has 3 equal sides.

'; explain[4] = '#5

Just as with the isosceles triangle, having equal sides creates equal angles across from those sides. Because all the sides are equal all angles are equal also.

'; explain[5] = "#6

A Triangle has 180 degrees total within it's angles. Therefore if an equilateral triangle has 3 equal angles, you can simply divide 180 by three to receive the answer. 180/3 = 60

"; explain[6] = "#7

If a base angle is measured at 60 degrees, then the other base angle must be 60 degrees. Therefore you've used 120 (60+60) degrees out of the 180 that a triangle has. 180 - 120 = 60degrees remaining for the vertex angle.

"; explain[7] = '#8

With 2 equal sides we already know that the triangle must be isosceles, Having an angle measure of 70 degrees does not matter.

'; explain[8] = '#9

Because an equalateral triangle has 3 equal sides, if one of the sides measures 20 you know the others must measure as 20 also in order to be equal.

'; explain[9] = '#10

Given that a base angle equals 45 degrees, we know that the other base angle must equal 45. 45+45 = 90. And we know that a triangle has 180 degrees in it. 180-90=90
