GeometryThe two lines on the left intersect each other at a right angle, which is 90 degrees.The two lines on the right are parallel,which means the never cross.The adjacent sides of a rectangle are perpendicular, which means they meet at a 90-degree angle. The opposite sides of a rectangle are equal and parallel, which means the never cross.The area of a rectangle is the length times the width.A circle is a 2 dimensional figure with a radius and a circumference, which is the distance around the circle.The area of a circle is pir squared, where r is the radius and pi is the ratio of a circle’s circumference to its diameter.A sphere is a three dimensional figure with a radius and a volume, which is 4/3 pi r cubed.All points on the surface of a sphere are equidistant from its center.A right triangle is a 2 dimensional figure with 3 sides, two of which are perpendicular.To find its area, multiply the lengths of the two perpendicular sides, a and b, and divide by two, A=1/2ab.1.A rectangle is a 2 dimensional figure with 4 sides.2.Which figure has a circumference
