Triangles
100
A pair of adjacent supplementary angles
What is a linear pair?
100
Equilateral triangle
What is a triangle that has all sides the same and of the same length?
100
Translation, Reflection, Dilation and Rotation
What are all the transformations ?
100
Shape that has 3 sides
What is a triangle?
200
An angle that measures less than 90 degrees.
What is an acute angle?
200
An angle greater than 90 degrees
What is an obtuse angle?
200
Similar figures are the same shape and have the same angle measurements but have proportional side lengths. Congruent figures are exactly the same (size, angle measurements and side lengths.)
What is the difference between similar and congruent figures ?
200
A triangle with all same side lengths
What is an equilateral triangle?
300
The point where two rays meet to form an angle
What is the vertex?
300
an angle that is exactly 180 degrees
What is a straight angle
300
a transformation that flips an image over a line of reflection
What is reflection?
300
A triangle that only has two same sides
What is an isosceles triangle?
400
An angle.
What are two rays that share an endpoint called ?
400
Protractor
What is used to measure angles?
400
1) From the center of rotation draw a line to one of the points on the preimage (e. Point A) and then draw a line to the corresponding point (e. Point A'). 2) Take a protractor and measure the angle
What is angle rotation?
400
A triangle with no equal sides
What is a scalene triangle?
500
An isosceles triangle has two sides of equal measure. An acute triangle is when all angle are acute or less than 90 degrees.
What is an isosceles and acute triangle ?
500
a segment, or ray that divides into smaller, equal angles
What is angle bisector?
500
a line (or lines) such that the image of the figure when reflected over the line is itself.
What is line symmetry?
500
Right triangle
What is one angle in a triangle that is equal to 90 degrees?
