2 angles whose sum is 180?
2 angles whose sum is 180 are called supplementery angles.an example of supplementary angles are two right angles.=)
What is the definition to acute triangle?
A triangle, all of whose angles are acute.A triangle, all of whose angles are acute.A triangle, all of whose angles are acute.A triangle, all of whose angles are acute.
Are polygons whose vertices can be paired so that corresponding angles are congruent and corresponding sides are proportional?
The fact that corresponding angles are congruent does not require corresponding sides to be proportional - except in the case of a triangle. For quadrilaterals, think of a square and rectangle.
How many sides in regular n-gon whose sum of interior angles is 1080?
sum of interior angles = (n-2)180=1080 1080/180=n-2 6=n-2 8=n
What are two angles with a sum of 180 degrees called?
They are called supplementary angles. See the related link below for more information.They are complementary angles that add up to 90 degrees
Two angles whose sides are opposite rays are?
Vertical angles
What is a quadrilateral whose opposite sides are parallel and congruent and whose opposite angles are congruent?
its a shape
What are a pair of adjacent angles called whose non-common sides are opposite rays?
A pair of adjacent angles whose non-common sides are opposite rays are called a linear pair. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
A pair of adjacent angles whose noncommon sides are opposite rays?
A pair of adjacent angles whose non-common sides are opposite rays are called a linear pair. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
What is veritcal angle?
It is 2 angles whose sides are opposite rays
What is a parellalogram?
It is a quadrilateral whose opposite sides are parallel and has no right angles
Two angles whose sides form two pairs of opposite rays are?
Vertical Angles
What is a tilted rectangle called?
A parallelogram.Types of parallelogram:Rhomboid - A quadrilateral whose opposite sides are parallel and adjacent sides are unequal, and whose angles are not right anglesRectangle - A parallelogram with four angles of equal sizeRhombus - A parallelogram with four sides of equal length.Square - A parallelogram with four sides of equal length and four angles of equal size (right angles).
What is a pallelogram?
A parallelogram is a quadrilateral whose opposite sides are parallel and has no right angles
What is two angles whose sides are opposite rays?
If I understand the question: Either pair of opposite angles formed by the intersection of 2 lines.
Is a parallelogram symmetrical?
In short, yes. A parallelogram is a quadrilateral with opposite sides parallel (and therefore opposite angles equal). A quadrilateral with equal sides is called a rhombus, and a parallelogram whose angles are all right angles is called a rectangle. And, since a square is a degenerate case of a rectangle, both squares and rectangles are special types of parallelograms.
Why do rhombus have equal opposite sides?
A rhombus has 4 equal sides and opposite parallel sides whose opposite interior angles are equal but none of them are 90 degrees otherwise it would be a square.
