    Classify the angles in the following exercises as acute, obtuse, right, or straight.

    Exercise \(\PageIndex{1}\)

    \(m\measuredangle = {32^ \circ }\)

    Exercise \(\PageIndex{2}\)

    \(m\measuredangle = {120^ \circ }\)

    Exercise \(\PageIndex{3}\)

    \(m\measuredangle = {180^ \circ }\)

    Exercise \(\PageIndex{4}\)

    \(m\measuredangle = {90^ \circ }\)

    Exercise \(\PageIndex{5}\)

    \(m\measuredangle = {110^ \circ }\)

    Exercise \(\PageIndex{6}\)

    \(m\measuredangle = {45^ \circ }\)

    Exercise \(\PageIndex{7}\)

    Use the given figure to solve for the angle measurements.

    Two lines intersect each other forming a right angle. A ray originates from the intersection point of the lines. The ray makes an acute angle, 5 x plus 4 with the horizontal line. The ray makes an acute angle, 39 x minus 2 with the vertical line.

    Exercise \(\PageIndex{8}\)

    Use the given figure to solve for the angle measurements.

    A horizontal line with two rays originating from its center. The first ray makes an angle, 3 x plus 2 with the horizontal axis. The angle formed between the two rays is labeled 3 x plus 7. The second ray makes an angle, 2 x plus 3 with the horizontal axis.

    Exercise \(\PageIndex{9}\)

    Give the measure of the supplement to \({89^ \circ }.\)

    Use the given figure for the following exercises. Let angle 2 measure \({35^ \circ }\).

    Two parallel lines, l subscript 1 and l subscript 2 are intersected by a transversal. The transversal makes four angles numbered 1, 2, 3, and 4 with the line, l subscript 1. The transversal makes four angles numbered 5, 6, 7, and 8 with the line, l subscript 2. 1, 2, 7, and 8 are exterior angles. 3, 4, 5, and 6 are interior angles.

    Exercise \(\PageIndex{10}\)

    Find the measure of angle 1 and state the reason for your solution.

    Exercise \(\PageIndex{11}\)

    Find the measure of angle 3 and state the reason for your solution.

    Find the measure of angle 7 and state the reason for your solution.

    Exercise \(\PageIndex{16}\)

    Find the measure of angle 8 and state the reason for your solution.

    Exercise \(\PageIndex{17}\)

    Use the given figure to solve for the angle measurements.

    Two lines intersect each other. One set of opposite angles is labeled 5 x minus 129 and 2 x minus 21.

    Use the given figure for the following exercises.

    Two parallel lines are intersected by a transversal. The transversal makes four angles with the line, l subscript 1. Two angles are unknown. Two opposite angles are marked 3 and 50 degrees. The transversal makes four angles with the line, l subscript 2. 8 and 50 degrees are exterior angles. 3 is the interior angle.

    Exercise \(\PageIndex{18}\)

    Find the measure of angle 3 and explain the reason for your solution.

    Exercise \(\PageIndex{19}\)

    Find the measure of angle 8 and explain the reason for your solution.
