1.02 Basic Constructions
Arc - ANS Is a part of a circle
Acute - ANS Less than 90°
Obtuse - ANS More than 90° but less than 180
Right - ANS Exactly 90°
Straight - ANS Ingles are similar to straight lines there is no bend like when you
straighten your arm so it lies flat as a line and measures exactly 180
Bisecting - ANS Cutting into halves
Steps to construct a congruent line segment to a given long segment using a compass
and straight edge are - ANS 1. Open the compass to it with that matches the given line
segment
2. Using a straight edge draw a line that is longer than the given segment was one end
point
3. Without changing the width of the compass use the compass to draw an arc on the
Ray from its end point
4. Draw a point at the intersection of the art and Ray which represents the distance
between the endpoints of the given segments
The steps to construct a congruent angle to give an angle J KL using a compass in
straightedge - ANS 1. Use a straight edge to create your Ray with end point T
2. Place the tip of your compass on the vertex of the given angle point K and swing an
arc that intersex both rays of the given angle
3. Keeping the compass the same with use the compass to draw an arc from the end
point
4. Draw the point of intersections between each arc in the ray or rays it intersects
5. Open the compass to the width of the intersections points between the ark in the two
rays of given angle JKL
