Why dont triangles and quadrailateral polygons end in 'gon'?
The words are Latin based, and the words tell us a lot about what the figures are. Triangles literally means "three angles" and there are indeed three angles in a triangle. A quadralateral means "four equal sides" and polygon means "many sides figure". So the many sided figure that has four equal sides might be a parallelogram, it might be a square, or a rectangle. The polygon merely says it's a shape. Get the picture? These are actually word pictures.
Why is it an isosceles triangle?
When a triangle has 2 sides that are equal in length it is isosceles from Latin and Greek words. Isosceles may also be a mathematical geometric shape with at least 2 sides having the same length.
Why is a trapezoid a quadrilateral but not a parallelogram?
Because a quadrilateral is any four-sided shape, whereas a parallelogram must have opposite sides and equal angels. A trapezoid only has two sides and equal angles.In other words, a parallelogram has 2 pairs of parallel sides but a trapezoid only has one pair (top and bottom).
How do you specify shapes?
You specify shapes by the number of sides (or edges, different name) they have. The suffix -gon at the end of a word show how many sides it has in the words. For example, an octagon has eight sides; so if you see a shape with eight sides, it's an octogon. All shapes are known as polygons, which means it has three or more sides.

Is a triangle with sides of 81516 a right triangle?
Not enough information - you need three sides to define a triangle. Once you have the three sides, check whether the square of the longest side is equal to the sum of the squares of the other two sides, in other words, c2 = a2 + b2, where "c" is the longest side. If it is the same, it is a right triangle; otherwise it isn't.

The Side-Side-Side (SSS) postulate states that if all three sides of one triangle are congruent to the corresponding sides of another triangle, then the two triangles are congruent. In other words, if the lengths of the three sides of one triangle are equal to the lengths of the corresponding three sides of another triangle, then the two triangles are congruent.
