1.A triangle with two sides of equal length is an isosceles triangle. The two equal sides of an isosceles triangle are known as ‘legs’ whereas the third or unequal side is known as the ‘base’.
2.parallelogram:A quadrilateral with 2 pairs of parallel sides.
3.A square is a parallelogram with four congruent sides and four right angles.in other words, a square is a rectangle and a rhombus.
4.A trapezoid is a quadrilateral with one pair of opposite sides parallel.it can have right angles(a right trapezoid),and it can have congruent sides (isosceles),but those are not required.
5.it is a rhombus.
6.An equilateral triangle has three equal sides and angles.
7.A triangle that has one right angle is called a right triangle.
8.A right triangle consists of two legs and a hypotenuse.the two legs meet at a 90°angle and the hypotenuse is the longest side of the right triangle and is the side opposite the right angle.there are a couple of special types of right triangles,like the 45°-45° right triangles and the 30°-60° right triangle.
9.A quadrilateral is a polygon that has exactly four sides.(this also means that a quadrilateral has exactly four vertices,and exactly four angles).
10.trapezoid-A quadrilateral with exactly one pair of parallel sides.
