Math CC7/8 – Be Prepared Bell Starter On Desk: In Your Planner: In your journal: SD 1.5 Design Challenge In your math journal, draw an acute and an obtuse angle using a protractor. Label the measurement. Have someone check your work! Can you give the complementary and supplementary angles for each?

Tasks for Today Warm Up – in journal HW questions?-Go over EXTENDING when measuring for accuracy Add to our Angle Relationship Map! Lesson 1.5 Begin HW?

Using your protractor, draw an acute angle. Estimate the angle And then measure the angle. Name your angle. Next, draw an obtuse angle. Estimate the angle and then Measure the angle. Name your angle.

Adding to Angle Map Include obtuse, acute

Draw a 1in. line and label points A and B What is the vertex of the given angle? Estimate/sketch the angle Measure the exact angle Measure the length of line BC. Connect A to C!

Variety of triangles – depends on where you put the angles and side What should you start with? Draw the 2 in. line Label 2 of the points Measure each angle on either vertex. Extend lines until they meet. Variety of triangles – depends on where you put the angles and side Natural place is to put the side between the two given angles

Can you visualize this polygon? What should you start with… angle or side length? Draw the 2 in. line Label 2 of the points Measure each angle on either vertex. What’s next? What do you know about the 2 sets of sides? Does it look like a parallelogram?

Cannot be done! Once sides KL and LM are drawn with the given conditions, the distance from K to M is greater than 1 in.
