Question

draw and label an angle to fit each description.

1. an obtuse angle, $angle y$
2. an acute angle, $angle jih$
3. a right angle, $angle 3$
4. a straight angle, $angle cde$

Explanation:

1. For ∠Y (obtuse): Draw two rays meeting at vertex Y, forming an angle between 90° and 180°, label the vertex Y.
2. For ∠JIH (acute): Draw two rays meeting at vertex I (with sides IJ and IH), forming an angle less than 90°, label vertices J, I, H.
3. For ∠3 (right): Draw two perpendicular rays meeting at the vertex labeled 3, add a right angle symbol, forming a 90° angle.
4. For ∠CDE (straight): Draw a straight line with vertex D (sides DC and DE), forming a 180° angle, label vertices C, D, E.

Answer:

1. Obtuse ∠Y: An angle between 90° and 180° with vertex labeled Y.
2. Acute ∠JIH: An angle less than 90° with vertex I, sides IJ and IH.
3. Right ∠3: A 90° angle with vertex labeled 3, marked with a right angle symbol.
4. Straight ∠CDE: A 180° straight angle with vertex D, sides DC and DE.
