Question

find the measures of the numbered angles in the isosceles trapezoid.
m∠1=□°

Explanation:

Step1: Recall Isosceles Trapezoid Angles

In an isosceles trapezoid, base angles are equal. The given angle (33°) and ∠1 are base angles (since the bases are parallel, marked by arrows).

Step2: Determine ∠1 Measure

Since base angles in an isosceles trapezoid are congruent, \( m\angle1 = 33^\circ \).

Answer:

33
