DISTANCE IN A COORDINATE PLANE

PRACTICE WITH DISTANCES
IN A COORDINATE PLANE

Use the distance formula to find the distance between the points given.

1. A to B

2. C to D

3. E to F

4. G to H

5. (0, 3) to (-7, 4)

CIRCLES IN THE PLANE

PRACTICE WITH CIRCLES

Find the equation of the circle.

1. Center at the origin, radius = 7 units

2. Center at the origin, radius = 1 unit

3. Center at the origin, radius = 15 units

4. (BONUS!) Center at (1,2), radius = 3 units

5. (BONUS!) Center at (-2,7), radius = 5 units

CLASSROOM CONNECTION

Identify three Standards at your grade level that focus on prior knowledge
necessary to understand the equation of a circle.

Identify a lesson in your textbook that addresses one of these Standards.
Discuss strengths of the lesson and modifications you might make (if any)
to increase understanding for all learners.
