19.  Angles 1 and 2 form a linear pair and are supplementary.  So to find m∠2, subtract m∠1 from 180o.  m∠2 = 180o - 135o = 45o.

Solution∠1 and ∠5 are corresponding angles, so they have equal measures. Find m∠5. The angle with measure 125 and ∠5 are supplementary.

Two lines in the same plane that do not intersect are called parallel lines. When a line intersects two parallel lines, several pairs of angles that are formed have equal measures.

When two lines intersect to form one right angle, they form four right angles. Two lines that intersect at a right angle are called perpendicular lines.

When two lines intersect at a point, they form two pairs of angles that do not share a side. These pairs are called vertical angles, and they always have the same measure.

The microstructure and properties of medium-carbon steel (0.45% C) are studied after torsional severe plastic deformation (SPD) at a high quasi-hydrostatic pressure and elevated temperatures of from 300 to 450°C. The initial treatment prior to the SPD is hardening for martensite. Analysis of the results shows that the SPD is effective for raising the characteristics of strength and microhardness at satisfactory ductility.

Solution The diagram shows that m∠1 = 90. ∠1 and ∠3 are vertical angles. Their measures are equal, so m∠3 = 90. ∠1 and ∠2 are supplementary.
