Does every combination of 2 sides add up to equal a greater number than the 3rd side? yes

Does every combination of 2 sides add up to equal a greater number than the 3rd side? no


'; explain[5] = '#6

Remember that the side length and angle measure go hand in hand. If the 3rd side is larger, than the angle will also be larger.


'; explain[6] = '#7

All it takes to prove congruency is 2 sides and an angle, or 2 angles and a side, so if we have 2 angles and 2 sides equal than the entire triangle is equal.


'; explain[7] = '#8

Angle size affects the length of the opposite side completely. If the angle gets bigger so does the opposite side.


'; explain[8] = '#9

The hypotenuse is the longest side on a right triangle.


'; explain[9] = '#10

If 2 triangles have 2 congruent sides but the 3rd side is not, then one of them has a larger 3rd side. If so, then it also has a larger angle which means that none of the angles are equal.
