It takes four times because 45+45=90+45=135+45=180. So all of those angles can make a straight line.
two, since a right angle is 90o & a straight line is 180o
A straight angle is a line which has an angle of 180 degrees therefore two right angles (90 degrees) make a line.
You can use straight angles to make sure countertops, or walls are straight and in a right formation.
Any two angles whose sum is equal to 90 degrees are called "complementary 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.
A straight angle is a line which has an angle of 180 degrees therefore two right angles (90 degrees) make a line.
A 180 Degree angle therefore a straight line.
Perpendicular line segments are line segments that intersect and make 90 degree angles.
180 degree angle or a straight 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.
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."
the middle of two line segments crossed (should make four 90 degree angles.
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.
An octagon cannot have 45-degree angles; the internal angles of a regular octagon are each 135 degrees. However, if you want to create an octagonal shape with 45-degree angles, you would need to design an irregular octagon. To form a shape with alternating 45-degree angles, you could use a series of straight lines that connect at 45-degree angles, ensuring that the overall shape closes back on itself to create eight sides.
