A triangle that has a 90-degree angle is...
A right triangle
50
How many lines does a plane contain?
an infinite number of lines
50
what is the definition of a side in shape?
A side is a straight line in between two corners of a shape.
50
what are complementary angles?
2 angles that have a sum of 90 degrees
50
what is the precise name of this shape?
A rhombus
100
what is the triangle with all its angles less than 90 degrees called?
An acute triangle
100
A line that passes through two parallel lines?
is called a transversal.
100
what is a polygon?
a closed plane figure made up of 3 or more-line segments that meet only at their endpoints
100
congruent angles are what?
a pair of angles that have the same measure
100
a hexagon equals to 720 degrees and has 6 sides, what is the measure of each angle?
120 degrees. 720/6 (for each side) = 120
225
What is an isosceles triangle?
a triangle with two if its sides congruent to each other
225
What is an angle bisector?
a line or ray that divides an angle into two congruent angles
225
What is a regular polygon?
A polygon that has all congruent sides and angles
225
An angle that is greater than 90 degrees and less than 180
Is called an obtuse angle
225
What is the segment that goes from the center of a circle to the edge called?
the radius. it's a line that passes from the center of a circle to the circumference. The diameter is a line that passes through the entire circle and its end points lie on the circumference
350
A triangle that has 3 congruent sides.
Is called an equilateral triangle
350
what are adjacent angles?
angles that are directly next to each other and do not overlap, in other words they have a common side and vertex
350
what is a convex polygon?
If each of the interior angles of a polygon is less than 180°, then it is called convex polygon.
350
what are interior angles?
4 angles that are formed on the inside of 2 parallel lines cut by a transversal
350
A tangent is what?
a line that touches the circle at one point, never entering the circles interior.
500
What is a triangle?
a three-sided polygon, having 3 vertices and 3 edges.
500
two congruent angles that are opposite angles formed by two intersecting lines are called what?
Vertical angles
500
What is the sum of the angle measures of a polygon?
2 less than the number of sides multiplied by the sum of the angle measures of a triangle- the sum of all interior angles of a regular polygon is calculated by the formula S= (n-2) × 180°, where 'n' is the number of sides of a polygon
500
Can you define a reflex angle?
it's an angle whose measure is more than 190 degrees but less than 360
500
A circular trampoline has a net surrounding it that is 50.24 feet long. What is the diameter of the trampoline?
16 feet. diameter can be found by dividing the circumference of the circle (the length of the net in this case) by n, which is 3.14
