Question 1, 3 and 4 by Aisyah Binte Mazlan

Q1) A square is a rhombus because all four sides of a square are equal in length. A square and a rhombus are both parallelograms with all the sides equal. However, a rhombus is not always a square, because the internal angles of a rhombus might not always be 90 degrees each.

Q3) The figure is a Trapezium. A Trapezium has two opposite lines that are parallel to one another, and two that are not. In the figure described, the two sides that are equal in length are the sides that are not parallel to each other, while the parallel lines are not the same length.

Q4) A square is a parallelogram because both pairs of opposite sides are parallel with each other. A square and a parallelogram both have parallel opposite sides. However, a parallelogram is not always a square, because the internal angles of a parallelogram might not always be 90 degrees each.
