Question

help me to solve the answer ​

Answer 1

Answer:

The origin creates 90 deegre angle, let's name 1,-3/2 as A ; -3,-7/2 as B; -4,-7/2 as C.

Step-by-step explanation:

Now if we create that triangle the Y axis passes through that triangle creating a quadrilateral so let's name the upper part P and the lower part Q

Now line PC is parallel to the X axis and the origin so the angle P is 90 degree. Now the sum of Angle Q and angle C is 180 degree ( as they create linear pair).

So 180 + 90 = 270

And a quadrilateral's sum of angles is 360

so 360-270 = 90 = Angle B

So proved that the triangle is right angled
