WebThe basic properties of a pentagon are given below which help to identify a polygon to be a pentagon. A pentagon has 5 sides and 5 angles. 5 diagonals can be drawn in a pentagon and this can be calculated using the formula, Diagonals of a pentagon: = n × (n − 3) ÷ 2 = 5 × (5 − 3) ÷ 2 = 5. The sum of all the interior angles of a pentagon ... Web5. Two of the vertices of a triangle are (3, 5) and (2, 1).

WebA trapezoid, also known as a trapezium, is a flat closed shape having 4 straight sides, with one pair of parallel sides. The parallel sides of a trapezium are known as the bases, and its non-parallel sides are called legs. A trapezium can also have parallel legs. The parallel sides can be horizontal, vertical or slanting. WebAnd we're done. So what we've done is-- it's interesting. We've shown if you have a parallelogram, opposite sides have the same length. And if opposite sides have the same length, then you have a parallelogram. And so we've actually proven it in both directions. And so we can actually make what you call an "if and only if" statement. WebIf it is a regular hexagon which has 6 equal sides then one can draw 3 parallelograms in the hexagon. What other shapes can a parallelogram be? Parallelograms are shapes that have four sides with two pairs of sides that are parallel. The four shapes that meet the requirements of a parallelogram are square, rectangle, rhombus, and rhomboid.
