Triangles
A plane figure bounded by three straight lines is called a triangle. The figure given below is a triangle ABC. The straight line AB, BC and CA are the line segments,
Therefore, the triangle ABC has: three sides, AB, BC and CA. Three anglesB and and three vertices A, B and C.
Remember the following about a triangle:
A Right Angle
When a straight line stands upright (perpendicular) on another straight line a right angle is formed. In the given figure, a straight line AB stands upright on the another straight line BC thus the ABC is formed is called a right angle. The line AB stands upright on BC called perpendicular line to BC and represented by AB -L BC. A right angle is represented by a box as shown in the figure. The measurement of a right angle is always (90 degree). In the given figure
Remember the following about a right angle:
