We have a square ABCD with sides = 1, and BE=1, and AE=CE.
What is the area of triangle ABE?
How can I solve this?
from the description we see that is isosceles. thus if we extend the line BE, it will cut the diagonal at a right angle. from this we can the angles that you see filled in.
now we simply use the formula
if you have any questions say so. i was kind of rushing through this and didn't explain much
