Question

Define:
1. perimeter
2. area
3. angle
4. triangle
5. quadrilateral

each defination contains 2 marks​

Answer 1

Answer:

1 A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference.

2 Area is the quantity that expresses the extent of a two-dimensional region, shape, or planar lamina, in the plane.

3 angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle

4 A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted {\displaystyle \triangle ABC}\triangle ABC

A quadrilateral is a polygon in Euclidean plane geometry with four edges (sides) and four vertices (corners).

Answer 2

Step-by-step explanation:

Perimeter is the distance around 2 dimensional shape

Area is the space occupied by a flat shape

Triangle is a closed curve or a polygon formed 3 line - segment

Angle is the figure formed by 2 rays meeting at a commen end point

Quadrilateral is a closed shape and a type of polygon that has 4 sides, 4 vertices and 4 angles
