What is the different angle measure of interior angle for all polygons?
The interior angles of a triangle must lie within the range (0, 180) degrees. For all other polygons, the interior angles must be in the range (0, 360) excluding 180 degrees.
Triangle sum theorem?
The sum of all inner angles within a triangle is 180 degrees.
Why is it not possible for a triangle to have 2 right angles in it?
Because the 3 angles within a triangle add must up to 180 degrees and 2 right angles add up to 180 degrees
How many degrees do the angles within a quadrilateral add up to?
The 4 interior angles of a quadrilateral add up to 360 degrees
Is a right triangle an equilateral triangle?
No. Within a triangle, the sum of all of the angles must equal 180 degrees. All three angles are acute (60 degrees) in an equilateral triangle, while only two are in a right triangle, the other being a right angle (90 degrees). There obviously could not be three right angles (270 degrees).
What is the different angle measure of interior angle for all polygons?
The interior angles of a triangle must lie within the range (0, 180) degrees. For all other polygons, the interior angles must be in the range (0, 360) excluding 180 degrees.
How do you calculate a angle within a triangle?
The three interior angles of any triangle add up to 180 degrees and they can be measured with a protractor.

What is answer of the angle measures of the pentagon?
The sum of the interior angles is 540 degrees. Within that constraint the angles can have any value.
What is the of the measures of the interior angles of a dodecagon?
The sum of the interior angles is (12-2)*180 = 1800 degrees. But within that constraint, each angle can be anything between (but excluding) 0 and 360 degrees.
What is well conditioned triangle in surveying?
a triangle that all the angles within it are between 30 and 120 degrees. an equilateral triangle is ideal
What is an interior angle of 20 sided polygon?
Think of the 20 identical triangles that are formed inside the polygon when you draw line segments from the centre of the polygon to each of the polygons corners. The angles of those triangles at the centre of the polygon add to 360 degrees, and there are 20 of them. Therefore, each of the angles of the triangles at the centre is 360 / 20 = 18 degrees. The angles within each triangle add to 180 degrees. Therefore the other two angles within each triangle, away from the centre of the polygon, add to 180 - 18 = 162 degrees. The two angles are equal. Therefore each angle is 162 / 2 = 81 degrees. Each interior angle of the 20-sided polygon consists of two of these angles. Therefore, the interior angle is 2 x 81 or 162 degrees.
Is there a relationship among the angles within a quadrilateral?
The interior angles of a quadrilateral must always add up to 360 degrees.
When using a protractor a student measure the sum of the interior angles in a triangle and obtain 176 degrees what is the percent error of this measurement?
3 The student can measure the given angles to within 2 degrees of the actual measurement and identify each angle, with 95% accuracy 2 The student is able to measure the given angles to within 10 degrees, and is able to identify the angles with 95% accuracy 1 Student is unable to correctly measure the given angles and/or identify the angles correctly
