What does Euclid's 5th postulate say?
If a straight line falling on two straight linesmakes the interior angles on the same side of it taken together less than two right angles , then the two straight lines , if produced indefinitely , meet on that side on which the sum of angles is less than two right angles.
Does a triangle and a line have equal 180?
If you took the three angles of a triangle and glued them on a piece of paper side by side the outer sides would make a straight line. A triangles three angles add up equal 180 degrees. A straight angle,line, equals 180 degrees.
How many sides and angles does a circle have?
One side and no angles. Unless you define a side as having to be straight line, then it is no sides. If a side can be a curved line by definition, then the number of sides is not an infinite number. If a side can have any curve then a circle has one side which connects into itself.
If one side on a straight line is 71 degrees then what is the other side equal?
The sum of the measures of angles on a straight line is 180 degrees. Therefore, if angle is equal to 71 degrees, the other is equal to 180 - 71 = 109 degrees.
What is a triangle with no angles called?
A triangle with no angles is called a degenerate triangle. It occurs when the three vertices are collinear, meaning they all lie on the same straight line. In a degenerate triangle, the side lengths sum up to zero.
How can you use the fact that the sum of the angles on a straight line is 180 to explain why the angle at a point are 360?
Draw any straight line through the point. The sum of the angles at the point are the sums of the angles on each side of the line - which are known to be 180o. Thus: the sum of the angles at the point = the sum of the angles of each side of the line = 180o + 180o = 360o The sum of the a
Two adjacent angles that form a straight line?
they are called supplementary angles. a straight line has 180 degrees each side and two adjacent angles forming 180 degrees are called supplementary angles.
What is the fifth postulate of Euclid's?
The parallel postulate: "That, if a straight line falling on two straight lines make the interior angles on the same side less than two right angles, the two straight lines, if produced indefinitely, meet on that side on which are the angles less than the two right angles."

How is constructing a perpendicular bisector different to constructing an angle bisector?
A perpendicular bisector is a straight line that divides a side of a triangle in two and is at right angles to that side. An angle bisector is a straight line that divides an angle of a triangle in two.
If one side on a straight line is 71 degrees then what is the other side equal?
The sum of the measures of angles on a straight line is 180 degrees. Therefore, if angle is equal to 71 degrees, the other is equal to 180 - 71 = 109 degrees.
What are Euclid's 5 postulates?
A straight line segment can be drawn by joining any two points.A straight line segment can be extended indefinitely in a straight line.Given a straight line segment, a circle can be drawn using the segment as radius and one endpoint as center.All right angles are congruent.If two lines are drawn which intersect a third in such a way that the sum of the inner angles on one side is less than two right angles, then the two lines inevitably must intersect each other on that side if extended far enough.
What are two angles you use in the classroom?
The answer will be a rug and a bookshelf. This is because they both are the same angle which are the right angle. They both have one straight line and one straight line is on the side and the other one is on the bottom.
How can tou tell the difference between complementary and supplementary angles?
The sum (addition) of two complementary angles is 90 degrees. Nestled side by side, they add up to a corner. The sum (addition) of two supplementary angles is 180 degrees. Nestled side by side, they add up to a straight line.
What is a triangle with no angles called?
A triangle with no angles is called a degenerate triangle. It occurs when the three vertices are collinear, meaning they all lie on the same straight line. In a degenerate triangle, the side lengths sum up to zero.
