It takes four times because 45+45=90+45=135+45=180. So all of those angles can make a straight line.

How many right angles are needed to form a straight angle?
A straight angle is a line which has an angle of 180 degrees therefore two right angles (90 degrees) make a line.
How many right angles would you put together to make a straight line?
two, since a right angle is 90o & a straight line is 180o
What are ways you use straight angles in real life?
You can use straight angles to make sure countertops, or walls are straight and in a right formation.
What does a 22 degree angle and a 68 degree angle make?
Any two angles whose sum is equal to 90 degrees are called "complementary angles".
How many 30 degree angles make a right angle?
10000
How many 60 degree angles can make a straight line?
3 times.
Why can't triangles be 180 degree angles?
A 180 degree angle is really a straight line. This would be easier to show with a drawing but I can't do that here.Note however that the three angles that make up a triangle together will equal 180 degrees.
How many right angles are needed to form a straight angle?
A straight angle is a line which has an angle of 180 degrees therefore two right angles (90 degrees) make a line.
An angle whose sides make a line is called?
A 180 Degree angle therefore a straight line.
How many right angles would you put together to make a straight line?
two, since a right angle is 90o & a straight line is 180o
What are perpendicular ling segments?
Perpendicular line segments are line segments that intersect and make 90 degree angles.
An angle whose sides make a line is a?
180 degree angle or a straight angle
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."
Why is it impossible for a triangle to contain an 180 degree angle?
The sum of the three included angles of a triangle always = 180 degrees. So if one angle = 180 degrees (a straight line) then the other two included angles will be = 0 degrees which cannot make a triangle.
What is a mathematical intersection?
the middle of two line segments crossed (should make four 90 degree 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.
Does a spring tide happen when the sun and moon are in line?
Yes, a straight line (180 degree angle). A neap tide is when the moon, Earth, and sun make a 90 degree angle.
