Worksheet PrintWorksheet 1. Find the measure of each interior angle of a regular decagon. 1,440 degrees 144 degrees 1,800 degrees 180 degrees 2. The sum of the interior angles of a polygon is 1,980 degrees. How many sides does it have?
When you use formula to find a single exterior angle to solve for the number of sides , you get a decimal (4.5), which is impossible. Think about it: How could a polygon have 4.5 sides? A quadrilateral has 4 sides. A pentagon has 5 sides. Interior Angles of a Polygons Worksheet ...
The Triangle Sum Theorem states that the sum of all angles in a triangle is ___. 45° 90° 180° 360° 3. Multiple Choice 5 mins 1 pt Find the measure of each angle indicated. 33° 136° 36° 31° 4. Multiple Choice 5 mins 1 pt Find the measure of each angl...
As the picture above shows, theformulafor remote and interior angles states that the measure of a an exterior angle∠A∠Aequals the sum of the remote interior angles. To rephrase it, the angle 'outside the triangle' (exterior angle A) equals D + C (the sum of the remote interior angle...
Exterior and Interior Angles of Triangles What are the Triangles? A triangle is a simple closed curve which is created by three line-segments. In geometry, any three points, specifically non-collinear, form a unique triangle and separately, a unique plane. The basic elements of the triangle ar...
摘要: We study the interior angle sums of translation and geodesic triangles in the universal cover of Sl2(R) geometry. We prove that the angle sum is larger then pi for translation triangles and for geodesic triangles the angle sum can be larger, equal or lessthan \pi....
