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.
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.
straight line indicates 180o
a straight line or supplementary angles...which equal to 180 degrees.
A straight line in angles represents 180 degrees.
That the corresponding angles are equal and that the alternate angles are equal and that angles on a straight line add up to 180 degrees.

Angles that add up to 180 degrees are called supplementary angles.
Yes because angles on a straight line add up to 180 degrees
It is a straight line which divides an interior angle of the triangle into two angles of equal measure.
a straight line or supplementary angles...which equal to 180 degrees.
All The Angles On A Straight Line Add Up To 180 Degrees.
A straight line in angles represents 180 degrees.
The sum of the angles in a rhombus equal a straight angle (180o).
1. Given two points there is one straight line that joins them. 2. A straight line segment can be prolonged indefinitely. 3. A circle can be constructed when a point for its centre and a distance for its radius are given. 4. All right angles are equal. 5. If a straight line falling on two straight lines makes 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 the angles are less than the two right angles. 6. Things equal to the same thing are equal. 7. If equals are added to equals, the wholes are equal. 8. If equals are subtracted from equals, the remainders are equal. 9. Things that coincide with one another are equal. 10. The whole is greater than a part.
