Geometry

100

How many degrees are in a circle?

360^o

200

Decide whether the following equations would graph parallel lines. Explain. 

y = 2x + 4

y = 2x - 5

Yes, they are parallel because they have the same slope (same coefficient in front of x)

300

Solve for the missing hypotenuse of a triangle with leg lengths of 8 and 15.

17

400

Do the side lengths form an acute, obtuse, or right triangle? 

7, 8, 9

They create an acute triangle 

500

Name the center and radius of a circle with equation: 

(x - 2)² + (y + 5)² = 64

Center: (2, -5) 

Radius: 8

Am I being irrational?

100

Tell whether the following number it rational or irrational

pi

Irrational 

200

Tell whether the following number it rational or irrational

sqrt(4)+sqrt(9)

Rational 

2 + 3 = 5

300

Tell whether the following number it rational or irrational

3 + (-sqrt(36))

Rational because 

3 + -6 = -3

400

Tell whether the following number it rational or irrational

Sqrt(8) + sqrt(81)

Irrational because the sqrt(8) is irrational

500

Tell whether the following number it rational or irrational

sqrt(3) + sqrt(2)

Irrational, because both pieces are irrational
