An isosceles trapezium has: One pair of unequal parallel sides. Two non-parallel equal sides. Two pairs of adjacent equal angles. Diagonals that are equal in length. One line of symmetry.
You can classify shapes based on their properties. Properties are qualities that a shape has. Examples of shape properties are: number of sides; length of sides; number of angles (corners)
Isosceles Trapezium: Has one diagonal that bisects the other. This means that one diagonal cuts the other diagonal in half. Additionally, the diagonals are not perpendicular to each other. Kite: Has one diagonal that is perpendicular to the other. This means the diagonals intersect at a right angle.
