Answer:
see below
Step-by-step explanation:
Rule 1: Equal Sides in a 45-Degree Right Triangle
This creates an isosceles right triangle, where the two legs being equal
Rule 2: Complementary Angle Relationship:
The tangent of a 45-degree angle is always 1. This is because the tangent is the ratio of the opposite side to the adjacent side, and in a 45-degree right triangle, these sides are equal. so it equals to 1.
