A triangle is made upof 3 angles and 3 segments (also called sides). The name of this triangle is ABC A C ∆ B Included angle is the first concept. Please draw and write this down! Angle C is included by and A AC BC C B An easy way to rememberthis is to think of allof the parts that makeup angle C. Please draw and write this down! Angle C is included by and A AC BC C B Included side is the second concept. Please draw and write this down! AC is included by and A angle A angle C C B An easy way to rememberthis is to look at the angles at the end of the segment (side). Please draw and write this down! AC is included by and A angle A angle C C B Opposite sides and angles is the third concept. Please draw and write this down! AB is opposite angle C. A C B An easy way to remember this is to image you have your back up against the corner at C. What wall would you be looking at? Please draw and write this down! AB is opposite angle C. A C you B Please draw and write this down! Angle A is opposite . A BC you C B Now that you have recorded the notes, I will ask you to answer the following questions regarding included and opposite. P Mark ALL that are correct. R Q opposite RQ included by PR and RQ included by RP and QP opposite QP Angle P is P Mark ALL that are correct. R We will use '<' (is less than symbol) as the angle symbol Q opposite < Q included by < Q and < R included by < R and < P opposite < P RQ is L J included by JK opposite < K opposite JL included by JL and JK K < J is L J Use the < symbol for angle and include a space. K JK is opposite L J Use the < symbol for angle and include a space. K List your answers alphabetically opposite to included by KJ is and Z X Y < Y is opposite XZ and included by XZ and YZ YZ is opposite < X andincluded by < Y and < Z XZ is included by < X and < Z, and opposite < Y < X is opposite YZ andincluded by XY and XZ L J use the < symbol for angle and include a space K opposite to included by KJ is H F G HG is opposite < F andincluded by HF and FG HF is included by < F and < H, and opposite < G < F is opposite HG and included by GH and FH < G is opposite HF andincluded by HG and FG |
