9.4: Congruent Inscribed Angles

I CAN identify and use properties of inscribed angles that subtend the same arc in a circle to solve problems

Math Starter

Remember …

Inscribed Angle - Inscribed angles subtended by the same arc are congruent (equal in measure).

Before we begin todays lesson, we need to learn a new property of a circle to help prove todays work.

With a partner, generate some ideas of what you think the measurement of arc CB is.

Jot some notes below. When you think you have an idea or maybe more, jot them on a sticky note and place them on the whiteboard.

What is the relationship with an inscribed angle that subtends the same arc?

Share your ideas with the class.

Complete the activity outlined in your notes titled Chord Property 3: Congruent Inscribed Angles.

We will go over the answers together.

Complete the Exit slip in your notes and hand in.
