1.4 Measuring Segments and Angles

I can use algebra to find segment lengths and angle measures Learning Target I can use algebra to find segment lengths and angle measures

Coordinate – The distance and direction from zero on a number line. Segment Length – The distance between two coordinates Congruent – equal. The same.

Find the length of each segment and tell whether the segments are congruent

Find the missing segment length

Yesterday we spent time solving algebraic equations Yesterday we spent time solving algebraic equations. That can come in handy when trying to find segment lengths, as well

Note : congruency marks More Vocab Midpoint- divides a segment into two congruent segments; a midpoint bisects the segment Note : congruency marks

I can use algebra to find segment lengths and angle measures Learning Target I can use algebra to find segment lengths and angle measures

Angle – formed by two rays with the same endpoint. Acute angle – measures between 0 and 90 degrees Right angle – measures 90 degrees Obtuse angle – measures between 90 and 180 degrees Straight angle – measures 180 degrees

Congruent angles – angles with the same measure Supplementary angles – two angles that add up to 180 degrees Complementary angles – two angles that add up to 90 degrees How to name an angle

Name it, Classify it Measure of an angle notationwhat does the little m mean?
