Geometry

Question 1

weight is what?

Answer 1

the pull of gravity on an object

Question 2

mass is what?

Answer 2

amount of matter that comprises an object.

Question 3

What is the equation for density?

Answer 3

Density = mass/volume

Question 4

What is a supplementary angle?

Answer 4

they equal 180’ (so if one angle is 45’ then the other is 135’)

Question 5

What is a complementary angle?

Answer 5

90’ (65’ is one 25’ is the other)

Question 6

what are congruent objects?

Answer 6

same shape and size

Question 7

what are similar objects?

Answer 7

same shape, but DIFFERENT size objects.

Question 8

Circle

- area
- circumference

Answer 8

area= pie r squared

circumference= 2 pie r

Question 9

Triangle

- area
- perimeter

Answer 9

area 1/2 b h

perimeter add up sides

Question 10

Parallelogram

- area
- perimeter

Answer 10

area-b h (draw a perpendicular line)

perimeter -add up sides

Question 11

Cylinder

- volume
- surface area

Answer 11

volume (area of the base) x (height)
(pie r squared) x h
surface area
add up all the area parts- circle circle rectangle.
(pie r squared) + (pie r squared) + (B x H)

when you need to k

Question 12

cone
what is the surface area?
what is the volume?

Answer 12

surface area- pie r side + pie r squared

volume- 1/3 pie r squared

Question 13

sphere

- area
- volume

Answer 13

Surface area= 4 pie r squared

volume = 4/3 pie r cubed

Question 14

boxes

Answer 14

surface area
sum of parts
volume
