Prisms/Cubes
How many sides or faces does a cube or cubic prism have?
6 sides and faces.
How many faces does a cylinder have?
3 faces(one curved surface and two circular faces)
How many faces does a cone have?
Two faces (the base and the curved face apply)
What are parallel lines
Two lines that never intersect.
Either of two angles whose sum is 180°.
V = Bh = /w x h
What formula do you use in order to find the volume of a cylinder?
V = Bh = lw x h
What formula do you use to find the volume of a cone?
V = 1/3 Bh
What does congruent mean?
When figures are identical in form.
What are complementary angles?
Two angles that sum up to 90°.
What formula do you use when trying to find the lateral area of a cube/prism?
LA = Ph = (2l +2w) x h
What formula do you use when attempting to figure out the lateral area of a cylinder?
LA = Ph = 2πr x h
What formula do you use to find the lateral area of a cylinder?
LA = πrl
What are perpendicular lines?
Lines that form a right angle when they intersect or cross.
What is an angle bisector?
A ray that divides an angle into two equal parts.
What formula do you use when determining the total area of a cube/prism?
TA = Ph +2B = (2l +2w) x h + 2lw
What formula do you use to find the total area of a cylinder?
TA = Ph +2B = 2πr x h + 2πr2
What formula do you use to find the total area of a cone?
TA = πrl + B
What defines a ray?
A ray has one endpoint on one side and infinitely extends into the other direction.
Angles that lie opposite to each other when two lines intersect.
What does the "P" stand for in the formulas?
The perimeter of the base
What does the π symbol stand for in the formulas?
Pi
What does the "B" stand for in the formulas?
Area of the base
What is a plane?
A plane is a flat surface of two dimensions that extends endlessly and has no thickness.
What are obtuse, acute, and right angles?
Obtuse angles are greater than 90°, acute angles are less than 90°, and right angles measure equal to 90°.
