Greater than 0 degrees and less than 90 degrees . Is this a acute ,right ,obtuse angle
acute angle
Two angles that are supplementary.The sum of the triangle is 180 degree.
supplementary angles
A polyhedron with two parallel congruent. A solid geometric figure with two faces.
it's lowest or a edge of a item. The number that is being used as a factor.
A angle that is 180 degrees. A straight angle changes the direction the point opposite way.
straight angles
This angle is less than 90 degrees. its smaller than a obtuse angle.
acute angle
all of the angles are less than 90 degree. Nothing is greater than 90 degrees
acute triangle
This angle is at a 90 degree angle
An angle that measures wider then 90 degrees and less then 180 degrees
A figure with straight parallel side and circular. it has the same cross section from one end to the other.
Is a three dimensional shape with a circular base. a curved surface to one single vertex.
All of the sides have the same length . It is mostly drawn of a little tic line in the middle of the segments.
congruent segments
It is in the same plane . Also the lines and points lie in the same plane too
A three dimensional space with a plane. cutting a object into slices that makes them parallel.
Cross section
a square or triangular base that has sloping sides. built of stone as a royal triangle.
each of the pairs of opposite angles made by two intersecting lines.A pair of non-adjacent angles formed by the intersection of two straight lines.
vertical angles
A triangle where all three sides are different in length.No equal sides No equal angles.
scalene triangle
A triangle which has all three of its sides equal in length.Three equal sides Three equal angles, always 60°.
Equilateral triangle
is a line segment where two such surfaces meet.In any geometric solid that is composed of flat surfaces.
is a line segment that links two vertices of a polygon that are not adjacent. a polygon which are not already joined by an edge.
