Geometric Terms 1
What is a point?
an exact location that is represented by a dot
Lines that never meet and never cross are called...?
parallel lines
What is an acute angle?
An angle that measures less than 90 degrees.
360 degrees is the measure for a...?
a circle
Find the measure.
I drew two angles sharing a vertex that measures 88 degrees. One of the angles measures 58 degrees. What is the measure of the other angle?
30 degrees
What is a line?
a straight set of points that has two arrows in both directions
Lines that meet or cross each other at one point are called...?
intersecting lines
What is an obtuse angle?
An angle that measures more than 90 degrees.
Tell me what type of angle the measure would be:
85 degrees
acute
Find the measure.
I drew two angles sharing a vertex. One of the angles measures 86 degrees. The other angle measures 62 degrees. What is the total measure of the angle?
148 degrees
Draw an example of a ray.
*should be a line with an endpoint on one end and an arrow on the other end*
Lines that meet or cross each other and form square corners are called...?
perpendicular lines
What is a right angle?
An angle that measures 90 degrees.
1/5 of a circle measures...?
72 degrees
Find the measure.
I drew two angles sharing a vertex that measures 111 degrees. One of the angles measures 78 degrees. What is the measure of the other angle?
33 degrees
Draw an example of a line segment.
*should be a line with two endpoints*
True or False: Intersecting lines have a symbol we can use to write math sentences describing lines.
False, only parallel and perpendicular lines have a symbol.
What is a straight angle?
An angle that measured 180 degrees.
2/3 of a circle measures...?
240 degrees
Find the measure.
I drew three angles sharing a vertex that measures 23 degrees. One of the angles measures 3 degrees. The other two angles have the same measure. What is the measure of the other two angles?
10 degrees
What is the difference between a line and a line segment?
A line has two arrows and a line segment has two endpoints.
True
Yes or No: Can a right angle be an obtuse angle?
No. A right angle is ONLY 90 degrees.
Tell me what type of angle the measure would be:
95 degrees
obtuse
Find the measure.
I drew 12 angles that each measure 15 degrees. What is the total measure of the angle?
180 degrees
