=Constructing an Angle With a Protractor=

To construct an angle using a protractor, follow the procedure listed below.

You will need a protractor and a pencil.

1) Draw one ray and mark the vertex. 2) Place the protractor so that the center is on the vertex and 0° is on the arm. 3) Measure from 0°, and mark a point at the degree measurement you are constructing. 4) Remove the protractor and draw the other ray of the angle.

=Constructing a Angle With a Compass=

 * Closest to 180 Degrees**

Follow the following instruction to play this game.

• Play in pairs or small groups. • Determine who goes first. • Player 1 rolls the three dice and finds the product of the three numbers rolled. • The product is the number of degrees of the angle. • Player 1 draws the angle rolled using a protractor and ruler. • Player 2 repeats. • Player 1 draws the next angle on the ray of the previous one and keeps a running sum of the angles as each is added. • Player 2 repeats. • Players take turns rolling the dice, drawing angles, and finding the sums. • A player stops rolling when they think their total angle is as close as it can get to 180°. • The winner is the player closest to 180°.
