Question

in the quadrilateral ABCD shown below the sides of ab and CD are parallel. M is the midpoint of the side BC. the lines DM and AB extended, meet at N. 1,Are the area of triangle DCM and triangle BMN equal? why?​

Answer 1

Answer:

The area of triangle DCM and BMN equal.

Step-by-step explanation:

in ∆DCM and ∆BMN,

CM=BM

if AB and CD parallel and BC it's intersector,

<NBM=<DCM

again,<BMN=<DMC[vertical angle]

so,∆DCM is congruent to ∆BMN

So, their area will be equal.
