1. Rectangle and Rhombus

In this figure, ABCD is a parallelogram and AECF is a rhombus.Triangle ABE and Triangle CDF are equilateral. If angle BAF = 84 degrees find

a) angle ecf
b) angle bec
c) angle abc

2. Re: Rectangle and Rhombus

What have you done so far to figure this out?

3. Re: Rectangle and Rhombus

I have figured out angle ecf = 24
angle bec = 144
Not really sure on that though.

4. Re: Rectangle and Rhombus

That's correct.

To work out the remaining angles remember that all the sides of a rhombus are equal length, and that all the sides of an equilateral triangle are equal. What do you notice about the remaining triangles?
