adjacent angles造句

• When two adjacent angles form a straight line, they are supplementary.
• Also, triangles with two equal sides and an adjacent angle are not necessarily equal or congruent.
• Specifying two sides and an adjacent angle ( SSA ), however, can yield two distinct possible triangles.
• Let " DEF " be the triangle formed by the intersections of the adjacent angle trisectors of triangle " ABC ".
• For example, two lines can intersect in no more than one point, intersecting lines have equal opposite angles, and adjacent angles of intersecting lines are supplementary angles.
• Angle " E " is therefore the adjacent angle of a right triangle with hypotenuse, adjacent side, and opposite side sin " ? " } }.
• *" Adjacent angles ", often abbreviated as " adj . " s ", are angles that share a common vertex and edge but do not share any interior points.
• These follow from the previous proposition by applying the fact that opposite angles of intersecting lines are equal ( Prop . 15 ) and that adjacent angles on a line are supplementary ( Prop . 13 ).
• Since in a parallelogram adjacent angles are supplementary ( add to 180?) and " ABC is a right angle ( 90?) then angles " BAD, " BCD, and " ADC are also right ( 90?); consequently ABCD is a rectangle.
• Adjacent angles which sum to a right angle, straight angle or full angle are special and are respectively called " complementary ", " supplementary " and " explementary " angles ( see " Combine angle pairs " below ).
