Right-click and use the context menu to specify x,y,z coordinate locations, distance, and direction. Note: Do not create the last two segments if you intend to use Square and Finish to close the shape and autocomplete the last two segments at right angles. To finish the feature, use one...
Solved Examples on Vertical Angles 1. Find the measure of∠DCE. Also, find the other missing angles. Solution: ∠DCE and ∠ACB are vertical angles. Vertically opposite angles are always equal. Thus, ∠DCE = ∠ACB = 65° Here, ∠ACB and ∠BCE are angles in a linear pair. ...
Z and F Angles c and a are calledz-angles, because if you follow the line from the top of c to the bottom of a, it forms the shape of a z (in red in the diagram above). a and a are said to beF-angles, because the line forms an F shape from the bottom of the upper angl...
解析 A。选项 A“square”是正方形,有四条相等的边和四个直角;选项 B“parallelogram”是平行四边形,对边相等;选项 C“rhombus”是菱形,四条边相等但不一定有直角;选项 D“trapezoid”是梯形,四条边不一定相等也不一定有直角。所以答案是 square。反馈 收藏 ...
