What is an angle?
An angle that looks like an "L"
A right angle
A key similarity between a square and rhombus
Four sides of the same length
All of my sides are the same length. What king of triangle am I?
An equilateral triangle.
What is a shape with 6 sides, vertices, and angles?
Hexagon
A point where two straight lines meet
What is a vertex?
An angle that is smaller than a right angle
An acute angle
The difference between a rhombus and parallelogram
The sides of a rhombus are the same length
I have one angle that is LARGER than a right angle. What kind of triangle am I?
An obtuse triangle.
Shapes with 4 sides, vertices, and angles
What is a quadrilateral?
2 straight lines that are always the same distance apart that will never meet
An angle that is larger than a right angle
An obtuse angle
Two quadrilaterals with the same number of identical angles
Square and rectangle
Two of my sides are the same length. What kind of triangle am I?
An isosceles triangle.
Shapes with 8 sides, vertices and angles
What is an octagon
What are sides, angles, and vertices?
If a triangle has one right angle, what kind of angles are the other two?
They are both acute angles
Three qualities ALL quadrilaterals have in common
Four sides, vertices, and angles
None of my sides are the same length. What kind of triangle am I?
A scalene triangle.
What is the area and perimeter of a square with 6 inch long sides?
Perimeter: 24 inches
Area: 36 inches squared
Quadrilateral with 1 pair of parallel lines
What is a trapezoid?
I am a shape that only has right angles. What am I?
square or rectangle
A quadrilateral with sides of four different lengths
An irregular quadrilateral
Is it possible: a triangle that is both an equilateral triangle and a right triangle?
Impossible! There needs to be at least one longer side to connect the two sides that intersect to form a right angle.
