The two lines on the left intersect each other at a right angle which is 90 degrees. The 2 lines on the right are parallel, which means they never cross.
The adjacent sides of rectangle are perpendicular, which means they meet at a 90-degree angle. The opposite sides of the rectangle are equal and parallel, which means they never cross. The area of a rectangle is the length times the width.
A circle is the 2 dimensional figures with radius and circumference which is the distance around the circle. The area of the circle is π R square, where r is the radius and Pi is the ratio of the circle’s circumference to its diameter.
A sphere is a 3 dimensional figure with the a ratio and volume, which is the three-fourth πR cube. All points on the surface of the sphere are equidistance from its center.
A right triangle is a 2 dimensional figure with 3 sides, 2 of which are perpendicular. To find its area, multiply the length of the 2 perpendicular sides, A and B and divided by 2, A equates one half A B.
