Construct $△ DEF$ in which $EF = 5 cm$ , $∠ E = ∠ F = 50 °$ . What kind of triangle is this?

Open in App

Solution

Step 1: Draw a line $EF = 5 cm$
Step 2: At point E draw $∠ E = 50 °$
Step 3: At point F draw $∠ F = 50 °$ and Line EP and FM intersect at point D

Hence, $△ DEF$ is formed.
Here two angles of a triangle are same which makes it an Isosceles triangle. In Isosceles triangle, any two angles of a triangle have same values.
