4. LEARNING TO USE THE SET OF TRIANGLES
A SET OF T RIANGLES CAN BE USED TO DRAW PARALLEL
AND PERPENDICULAR LINES IN AN EASY AND PRECISE
WAY.

5. LEARNING TO CREATE ANGLES WITH THE
SET OF TRIANGLES
DRAW ALL THESE ANGLES IN YOUR NOTEBOOK
USING ONLY T HE SET OF T RIANGLES:
-30º, 45º, 60º, 90º, 120º
-150º (90º+60º)
-135º (90+45º)
-105º (60+45º)
-75º(45º+30º)

-Parallel lines never intersect because all their point are
equidistant.
-When two lines cross forming four right angles they are called
perpendicular lines.
-Oblique lines are neither parallel nor perpendicular.
-Angles which share one side and the vertex are adjacent.
-Two angles are complementary if they add up to 90 degrees and
they are sumplementary angles if they up to 180 degrees.
-A right angle measures 90 degrees, an obtuse angle is greater
than 90 degrees and an acute angle less than 90.
