How many 45 degree angles can make a straight line?
It takes four times because 45+45=90+45=135+45=180. So all of those angles can make a straight line.
Does the sum of the measure of the angles is 180 degrees?
Only in some cases: 1. The angles are supplementary 2. The angles are at a single point on a straight line and all on the same side of it 3. The interior angles of a triangle. and a few more complicated scenarios. Otherwise, the answer is NO.
How much do all the angles of an octagon add up to?
Exterior angles add up to 360 degrees Interior angles add up to 1080 degrees
How many degrees does a rectangle to add to?
all the angles are right angles (90 degrees) and add to 360 degrees
What is true about any regular polygon?
The following is true of all polygons: -It is made up of straight line segments -It is 2-D -It is a closed figure, and thus has an area -Its angles add up to (n-2)x180 when n is the number of sides it has, unless it has a crossover. But "regular", when referring to a polygon, means that all of its sides are the same length, which also means that all of its angles are the same size; thus also: -It is convex. -its sides are congruent. -its angles have equal measures
Why will a scalene triangle tesselate?
Because angles on a straight line add up to 180 degrees and the 3 interior angles of any triangle add up to 180 degrees. So it follows that all triangles will tessellate.
Do all straight angles measure 180 degrees?
Yes; because a straight line is 180*
What does a perpendicular line look like?
A perpendicular line is a straight line that intersects another straight line at right angles or 90 degrees on all four sides.
What angle is supplementary?
A supplementary angle is one of multiple angles (usually two or three) that add up to 180 degrees. Remember, a straight line is 180 degrees, therefore, when all of the angles are added together they should equal 180 degrees, and be the equivalent of a straight line. They DO NOT have to be right next to one another to be supplementary to one another.
How many 45 degree angles can make a straight line?
It takes four times because 45+45=90+45=135+45=180. So all of those angles can make a straight line.
What do all angles in a triangle add up to?
All angles of any Triangle add up to 180 degrees. This only works on straight sided Triangles. By Akwon98 from a christian school in belrose NSW
What is the highest degree angle?
180 is a straight line, so all angles have to be less than that.
A figue has 2 right angles and 3 line segments is this a triangle?
No, not with two right angles. All the angles in a triangle add up to 180, you have that in two angles.
What do all the angles on a perpendicular line add up to all together?
i dont know but i think 360
What are 3 attributes of a triangle?
all the lines on a triangle are equal and the opposite sides are parallel
How do you work out the exterior angles of a nine sided shape?
Draw lines a little futher than the original lines and you will notice that there is an angles on a straight line question. Measure with a protractor or if not drawn to scale divide 360 by 9. if answering on a straight line then make sure it adds up to 180 degrees. With the 360 divided by 9, the bigger angle should be the interiorangle and the smaller the exterior. The exterior angles should all add up to 360 degrees!
Does an ellipse have 4 straight angles?
An ellipse is a conic section, a curving line which is the path of a point that moves in such a way that the sum of its distance from two fixed points is constant.... so no - there are not 4 straight angles in an ellipse, nor any straight bits at all.
