74 Mensuration & area of plane figures 1. Plane Figure: Any figure bounded by three or more straight lines or bounded by a closed line is a Plane Figure. The space closed within that figure is called its Area. The measurement of the length of the lines enclosing the space called its Perimeter.Here are some solved examples based on the formulas of the area as well as perimeter of different shapes. Example 1: If the radius of a circle is 21cm. Find its area and circumference. Solution: Given, radius = 21cm. Therefore, Area = π × r 2. A = 22/7 × 21 × 21. A = 1386 sq.cm. Circumference, C = 2πr C = 2 x 22/7 x 21 = 132 cm. Example 2:rotation (turn) the movement of a figure by turning it around a point, or vertex. Tessellation. a repeating pattern of closed figures that covers a surface with no gap and no overlaps. polyhedron. a solid figure with flat faces that are polygons. prism. a polyhedron that has two congruent polygons as bases. base.Perpendicular lines, on the other hand, are two lines that intersect at a right angle (90 degrees). So, while both terms refer to the relationship between two lines, they are different relationships. Try it yourself with these exercises: Identify parallel and perpendicular lines. Draw parallel and perpendicular lines.Level up on all the skills in this unit and collect up to 700 Mastery points!

For example, if a triangle has a base of 10 cm ‍ and a height of 8 cm ‍ , its area is A = 1 2 × 10 × 8 = 40 ‍ square centimeters.Area is defined as the total space taken up by a flat (2-D) surface or shape of an object. The space enclosed by the boundary of a plane figure is called its area. The area of a figure is the number of unit squares that cover the surface of a closed figure. Area is measured in square units like cm² and m². Area of a shape is a two dimensional ...AP State Syllabus 8th Class Maths Solutions 9th Lesson Area of Plane Figures Exercise 9.2. Question 1.

No, the triangles are not necessarily congruent. Two quadrilaterals are congruent. One has vertices P, N, O, and M, and the other has vertices S, T, V, and U. These corresponding congruent parts are known: OM ≅ TS. ∠P ≅ ∠U.…
