Distance/Midpoint

100

Midpoint Formula:

Distance Formula:

M=((x₁+x₂)/2,(y₁+y₂)/2)

d=sqrt (x₂-x₁)²+(y₂-y₁)²

JK has endpoints J(-1, 10) and K(-5, 2). MN has endpoints M(9, -7) and N(1, -3). Is JK ≅ MN ?

yes; both 8.94

If D is the midpoint of CE , CD = 9x – 7, and

DE = 3x + 17, find CE.

x= 4

CE= 58

Angle Relationships

100

What do we call opposite angles formed by two intersecting lines?

vertical angles

200

what are two adjacent angles that sum to 180 degrees?

linear pair

300

The measures of two vertical angles are (6x+29) and (8x-5), solve for x.

x=17

400

If ∠A and ∠B are complementary angles, m∠A = (2x + 11)°nand m∠B = (10x – 17) °, find m∠A.

x=8 

m∠A= 27 degrees

500

If ∠N and ∠P are supplementary angles, m∠N = (x + 3)° and m∠P = (7x – 15) °, find m∠P.

x= 24

m∠P = 153 degrees
