How many circle theorums are there?
7 circle theorums 1 the angles between a tangent and a radius is 90 degrees 2 the angle at the origin is double the angle at the circumfrence 3 the oppsite angles in a cyclic quadrilateral add up to 180 degrees 4 the angle of a trianle in a semi circle is 90 degrees 5 the alternate angles subtended at a segment are the same 6 the tangents are the same length from the same point of origin. 7 the alternate angle at a tangent and a triangle is the same.
How many degrees in a 18 angle polygon?
Interior angles add up to 2880 degrees
Are alternate interior angles complementary?
Not NecessarilyAlternate interior angles are congruent, or equal. They have the same angle measure, while complementary means they add up to 90 degrees. Therefore, the only time alternate interior angles are complementary is when they are exactly 45 degrees.
How many degrees does a trapezoid angle carry?
The 4 interior angles of a trapezoid add up to 360 degrees
What is the sum of the angle measure of the regular pentagon?
Each exterior angle measures 72 degrees and they add up to 360 degrees Each interior angle measures 108 degrees and they add up to 540 degrees
