To prove that
, we can use the side-angle-side (SAS) congruence criteria.
To prove that triangle EAB is congruent to triangle DCB, we need to show that they have congruent sides and congruent angles.
Since
and
are both right angles, they are congruent. This is because all right angles are congruent.
Next, we can look at the sides. We know that AB = CD because corresponding sides of congruent triangles are congruent.
Also, EA = CB because they are both parts of the same line, so they have the same length.
Therefore,
by the side-angle-side (SAS) congruence criteria.
The probable question may be: "If
and
are right angles, how do you prove
?"
