Lines
two lines that are the same distance apart and will never touch
What are parallel lines
This is the term for a 90 degree angle
What is a right angle
This is what "tri" means
What is 3
This is the number of sides on a quadrilateral
What is 4
When two right angles are next to each other, this is the total amount of degrees
What is 180 degrees
lines that intersect to form a right angle
What are perpendicular lines
An angle that is less than 90 degrees
What is an acute angle
A triangle with angles that all are less than 90 degrees.
What is acute triangle
This quadrilateral has 4 right angles and 4 EQUAL sides
What is a square
A student drew a right angle. This angle is split into 2 smaller angles. One angle is 38 degrees. The other angle is
What is 52 degrees
*Remember a right angle equals 90, so to find the missing angle you need to subtract
90 - 38 = 52
this has one endpoint and continues in one direction forever
What is a ray
an angle that is greater than 90 degrees
What is an obtuse angle
A triangle with one angle greater than 90 degrees
What is obtuse triangle
This is a quadrilateral with two pairs of opposite sides parallel and 4 right angles
What is rectangle
One angle measures 28 degrees.
One angle measures 143 degrees.
The combined angle of these two angles is
What is 171 degrees
This part of a line has 2 endpoints
What is a line segment
this is the number of degrees in a straight angle
What is 180 degrees
A triangle with a 90 degree angle
What is right triangle
This is a quadrilateral with two pairs of opposite sides parallel and all sides the same length. (it does not have to have right angles)
What is a rhombus
One angle is 65 degrees.
Another angle is 87 degrees.
When the angles are combined, they make this type of angle
What is an obtuse angle
*65 + 87 = 152
152 degrees is an obtuse angle
These lines cross but do not make square corners
What are intersecting lines
This is used to measure angles
What is a protractor
These are the points on a triangle
What is vertex or vertices.
This is a quadrilateral with only one pair of opposite sides parallel
What is a trapezoid
An obtuse angle is drawn. It measures 125 degrees. It is split into three smaller angles.
The first angle is 63 degrees.
The second angle is 25 degrees.
The measure of the third angle is
What is 37 degrees
Remember if the total angle from start to end is 125 degrees, and you know each of the smaller angles then you need to subtract to find the missing angle.
125 - 63 = 62
62 - 25 = 37
