A triangle will have perpendicular lines if it has a little square where two lines intersect to indicate there's a right angle there or if someone tells you that the triangle is a right triangle. Quadrilateral Lesson for Kids: Definition & Shapes. A quadrilateral is a polygon that has exactly four sides. All rights reserved. If two lines \(\overline{AB}\) and \(\overline{CD}\) are perpendicular to each other, we represent it using the notation \( \mathbf{ \overline{AB} \perp \overline{CD}}\). They usually have zero pairs of perpendicular lines. We know that many types of quadrilaterals, such as the trapezoids, a rhombus, rectangles, and all the regular polygons (except for the triangle), have parallel sides. Parallelogram: A parallelogram is a flat figure. Also opposite sides are parallel and of equal length. This is because each shape has a total of 360 degrees for the sum of its angles. This is because the rectangle that the sides are made up of has 90-degree angles and meets with the top and bottom at a 90-degree angle.
