JH: When you say angle AOB, do you mean the interior angle
or the exterior angle?
P]AOB is equal to the interior angle
P of the spherical triangle [delta]APB.
The terms deflection angle and interior angle
are used to describe two of the types of angles used in surveying.
He tried to determine the angle measurement of the decagon's larger interior angle
by using symbolic numeral manipulation; he subtracted 180[degrees] - 36[degrees] = 144[degrees], but he could not decide what to do with the result.
The interior angle
at F shrinks while those at A and B grow, and we need to find the particular values for A, B, and F that satisfy the third geodesic goal mentioned in the text.
Table 9-1 illustrates that two types of data must be collected, the length of the side and the interior angle

Since m[angle]DPQ = m[angle]PQR, (because trapezium PQC'D' is a reflection of trapezium PQCD along the line segment PQ) and m[angle]DPQ = m[angle]RPQ (because alternate interior angles
are congruent when a transversals intersects two parallel lines), APQR is an isosceles triangle with m[angle]PQR = m[angle]RPQ.
We walked to the second platform and took even more interior angles
of the labyrinth of ironwork.
Perhaps, if we could have such an acquaintance, we could know directly and unhypothetically that its interior angles
sum to two right angles.
The quadrilateral's interior angles
always add up to 360
Small letters denote the sum of the interior angles
in triangles and quadrilaterals.
All students were given the exact instructions on using pattern blocks to understand the relationship of interior angles
in various polygons.
which satisfies the property that for any triangle T with interior angles
[alpha], [beta] and [gamma], there exists a triangle T* whose sides have lengths f([alpha]), f([beta]) and f([gamma]).
5) Why is the sum of the measures of the interior angles
of a triangle 180[degrees]?
