1. Linear pairs are adjacent angles.
☞ [tex]\large\bold\green{\tt{always\:true}}[/tex]
☞ Linear pairs are pairs of adjacent angles that form a straight line (180°)
2. Adjacent angles form a linear pair.
☞ [tex]\large\bold\orange{\tt{sometimes\:true}}[/tex]
☞ Sometimes, adjacent angles form a linear pair, but in some cases, they don't.
3. Vertical angles are congruent angles.
☞ [tex]\large\bold\green{\tt{always\:true}}[/tex]
☞ Vertical angles are angles opposite each other when two lines intersect so they are always congruent.
4. Parallel lines intersect at a certain point.
☞ [tex]\large\bold\red{\tt{never\:true}}[/tex]
☞ Parallel lines never intersect with each other even if they are extended.
5. Adjacent angles are supplementary.
☞ [tex]\large\bold\orange{\tt{sometimes\:true}}[/tex]
☞ Some adjacent angles form a linear pair which are supplementary angles but some don't.
6. Supplementary angles are linear pair.
☞ [tex]\large\bold\green{\tt{always\:true}}[/tex]
☞ Supplementary angles are angles in which the sum of their measures is 180° and a linear pair also measures 180°.
7. Supplementary angles can be more than two angles.
☞ [tex]\large\bold\red{\tt{never\:true}}[/tex]
☞ Supplementary angles are never more than two angles.
8. Complementary angles are a pair of acute angles.
☞ [tex]\large\bold\green{\tt{always\:true}}[/tex]
☞ Complementary angles are angles in which the sum of their measures is 90° so they are always acute angles.
9. Angles forming a linear pair are supplementary.
☞ [tex]\large\bold\green{\tt{always\:true}}[/tex]
☞ Linear pairs form a straight line which is 180° so they are always supplementary.
10. The measures of complementary angles have a sum that is equal to the measure of a right angle.
☞ [tex]\large\bold\green{\tt{always\:true}}[/tex]
☞ Complementary angles are angles in which the sum of their measures is 90° and a right angle is also 90°
