Answer
Not Congruent
Work Step by Step
Given
△ABC is an obtuse triangle with obtuse angle A and
△DEF is an acute angle triangle.
Step 1 we need to compare the area We know area of
△= 1/2 bh
therefore area of
△ABC = 1/2* AB * H
=1/2 * 8 * 6
therefore area of
△ABC = 24$unit^{2}$
area of △DEF = 1/2* DE * H
=1/2 * 8 * 6
therefore area of △DEF = 24$unit^{2}$
area of △ABC = area of △DEF
△ABC is not congruent to △DEF even though there areas are congruent.
