Given that , , ,
and the point , determine the measure of .
Step 1: Find .
Since and are congruent,
is an isosceles triangle. In any isosceles
triangle, the angles opposite to the congruent sides are
Write an equation to represent the sum of angle measures in
. Let represent and ,
and solve for .
Step 2: Find .
Since and are parallel to
each other and crossed by transversal ,
and are corresponding angles with the same
