Can someone please explain to me in an easy way to understand how i can do these proof questions, i really hate geometry.
1. Angles MXA and CXB are congriuent as they are vertical angles.
2. Angles AMX and CBX are congruent as they are alternate interior angles for the line BM between the parallel lines AD and BC.
Hence triangles AXM and BXC have two congruent angles (and so the third angles in each triangle are also congruent to one another as the angle sum in any triangle is 180 degrees) and so are similar.
For ii), use i)
Since AXM and BXC are similar, the ratio of the sides is the same :
But M is the midpoint of AD. Then AM=AD/2. Since it's a rectangle, AD=BC.
--> AX/XC=1/2, 2AX=XC
