1. Name all parts of a 2-Dimensional shape:
Sides, angles, vertices
100
1. What are the parts of a 3D shape?
face, vertex, edge (if you added base you get an EXTRA 100 points!)
100
1. Two lines that are always the same distance apart and never touch are called ___________________
parallel
100
What is the name of the "cute" angle that is LESS than 90 degrees?
an Acute angle
100
How many sides, angles and vertices does a triangle have?
3, 3, 3
200
2. What 2D shape has 5 sides, 5 vertices, 1 acute angle and 4 obtuse angles?
a pentagon
200
2. How many faces does a cube have?
6
200
What are the three ways parallel lines can run?
diagonal, vertical, horizontal
200
What is the name of the angle that greater than 90 degrees?
Obtuse
200
What is the name of the triangle with 3 acute angles?
An acute triangle!
300
3. Draw and name two different quadrangles.
rhombus, square, rectangle, trapezoid, parallelogram
300
3. Does a pyramid have more vertices or edges?
- edges (5 vertices, 8 edges)
300
Write both names for the segment Mrs. Geier has drawn on the board.
segment AB AND segment BA
300
name AND draw the angle that is exactly 90 degrees
a right angle (look at Mrs. Geier's board to check your drawing)
300
Name the triangle with 3 equal sides
Equilateral triangle
400
4. Is a circle a polygon? Why or why not?
No because it only has one side and it is curved, not straight.
400
4. What shape has 2 curved edges?
- a cylinder
400
Are these lines intersecting (look at Mrs. Geier's board)? WHY or why not?
Yes, because if they were to continue on they would eventually intersect.
400
Name one 2D shape with at least two right angles
Square or rectangle
400
Name the triangle with two equal sides
Isosceles triangle
500
5. What does a shape need to have in order to be a polygon?
- 3 or more sides - all sides are straight - the shape is "closed" or the sides all connect
500
5. What are the 3 dimensions we can measure on a 3D shape? (you can draw a picture if you need to!)
Height (how tall), width/length (how wide), depth/thickness
500
5. Look at Mrs. Geier's board: Name each item.
ray, line, line segment, point
500
What is the name of the angle that is exactly 180 degrees?
a straight angle
500
Look at Mrs. Geier's board...name that triangle AND be ready to explain how you know.
Scalene-no three sides are the same length
