corresponding angles

[′kär·ə‚spänd·iŋ ′aŋ·gəlz]
(mathematics)
For two lines, l1 and l2, cut by a transversal t, a pair of angles such that (1) one of the angles has sides l1 and t while the other has sides l2 and t ; (2) both angles are on the same side of t ; and (3) the angles are on the same sides of l1 and l2, respectively.

Ic] values of carbon/epoxy specimen of the corresponding angles of layer reinforcement in delamination area: 0//0, 0//90, 0//+ 45 and + 45//- 45.
He attempted to prove the proposition, "the corresponding angles (the degrees of corresponding angles) formed by two parallel straight lines and a straight line that is not parallel to them are the same" but failed.
From the equation (6) there is also possible to derive corresponding angle for the tangent deviation [alpha]:
The corresponding angles for the handles on this box ranged from 7[degrees] to 35[degrees] and from 50[degrees] to 83[degrees], respectively.
That is, their corresponding angles are congruent and their sides are proportional.
In contrast, the corresponding angles of a perfect octahedron are 180 [degrees], 90 [degrees], and 90 [degrees], and the corresponding distances are 2, 1.
For example, in explaining why all of the angles measured 135[degrees], one student wrote (refer to Figure 6): "If angle BDQ is 45 degrees, then angle MQP is 45 degrees, because corresponding angles are congruent where parallel lines are present (parallel lines are present because of the square).
Some had to be helped because they used a dead-end strategy, matching corresponding angles from the small and big triangles as in figure 6.
Thus, if three sides of one triangle are congruent to three sides of another triangle, then the corresponding angles are congruent, and so the triangles are congruent.
