Lets solve some problems relating to angles.
Look at the in focus question below. What do you think the value is of the ?
Lets Learn what the angle would measure.
What do the angles in each corner of a rectangle measure?
That's right. It is 90 degrees.
If we fold this corner and we know x measures 40 degrees so 90 - 40 = 50 degrees.
Since the rectangle has been folded, if we divide 50 by 2 we know each one would measure 25 degrees.
Now, try the guided practice section below.
