Observe all the four triangles FAB, EAB, DAB and CAB as shown in Fig. 9.28: All triangles are congruent. Is the given statement true or false?
&Solution:
The figure represents four triangles FAB, EAB, DAB and CAB
Given, all triangles are congruent.
We have to determine if the given statement is true or false.
From the figure,
We observe that all triangles have the same base line
Their other lines are not equal to each other.
Therefore, the triangles are not congruent.
✦ Try This: Find the area of the parallelogram with base 6 cm and corresponding height 8 cm
Given, base of parallelogram = 6 cm
Corresponding height = 8 cm
We have to find the area of the parallelogram.
Area of parallelogram = base × corresponding height
= 6 × 8
= 48 cm²
Therefore, the area of the parallelogram is 48 cm².
