NOTE: Squares, Rectangles and Rhombuses are allĪ trapezoid (called a trapezium in the UK) has a pair of opposite sides parallel.Īnd a trapezium (called a trapezoid in the UK) is a quadrilateral with NO parallel sides: Also opposite anglesĪre equal (angles 'A' are the same, and angles 'B' The ParallelogramĪ parallelogram has opposite sides parallel and equal in length. In other words they 'bisect' (cut in half) each other at right angles.Ī rhombus is sometimes called a rhomb or a diamond. The RhombusĪ rhombus is a four-sided shape where all sides have equal length (marked 's').Īlso opposite sides are parallel and opposite angles are equal.Īnother interesting thing is that the diagonals (dashed lines) meet in the middle at a right angle. The SquareĪ square has equal sides (marked 's') and every angle is a right angle (90°)Ī square also fits the definition of a rectangle (all angles are 90°), and a rhombus (all sides are equal length).

The little squares in each corner mean 'right angle'Ī rectangle is a four-sided shape where every angle is a right angle (90°).Īlso opposite sides are parallel and of equal length. Let us look at each type in turn: The Rectangle Some types are also included in the definition of other types! For example a square, rhombus and rectangle are also parallelograms. There are special types of quadrilateral: They should add to 360° Types of Quadrilaterals Try drawing a quadrilateral, and measure the angles. interior angles that add to 360 degrees:.If you want to delete multiple shapes, select the first shape, press and hold Ctrl while you select the other shapes, and then press Delete.(Also see this on Interactive Quadrilaterals) Properties To open Edit Points mode with keyboard shortcuts, select the shape and then press Alt + JD, E, E.Ĭlick the shape that you want to delete, and then press Delete. To cancel the change to the point and line segments, press Esc before releasing the mouse button. A corner point joins two line segments with one segment going off in a different direction. Once you stop dragging the point will be changed to a corner point. To have the point treated as a corner point, press Alt while dragging either of the handles attached to the point. A straight point joins two line segments of different lengths. Once you stop dragging the point will be changed to a straight point. To have the point treated as a straight point, press Ctrl while dragging either of the handles attached to the point. A smooth point joins two line segments of equal length. Once you stop dragging, the point will be changed to a smooth point. To have the point treated as a smooth point, press Shift while dragging either of the handles attached to the point. To delete a point, click the point while pressing Ctrl. To add a point, click the shape outline while pressing Ctrl.

A vertex is the point, indicated by a black dot, where a curve ends or the point where two line segments meet in a freeform shape. On the Shape Format (or Format) tab, click Edit Shape, and then click Edit Points.ĭrag one of the vertexes that outline the shape. For example, you edit points when you need to lean a triangle over to the right. To close the shape, click near its starting point. To leave the shape open, double-click at any time. To finish drawing the shape, do one of the following: To draw a straight segment with the Freeform tool, click one location, move your pointer to a different location, and then click again to draw a curved segment, keep your mouse button pressed as you drag to draw. Ĭlick anywhere in the document, and then drag to draw. To draw a shape that looks like it was drawn with a pen by hand, or to create smooth curves, click Scribble. To draw a shape that has both curved and straight segments, click Freeform. On the Insert tab, in the Illustrations group, click Shapes.
