HUGH JOHN MACDONALD Geometry “Polygons and Angles” NAME:_____________________________ ROOM #________ Page 1 GEOMETRY “POLYGONS AND ANGLES” HOW CAN YOU BE SUCCESSFUL Word Webs: (What I know/pre-test) (What I have learned/post test) • Triangle (page 3) 5 marks • Quadrilateral (page 4) 5 marks • Pentagon (page 8) 10 marks “Angles Can Be A Real Rip-off": (making discoveries) • Triangle (page 7) 10 marks • Quadrilateral (page 7) 10 marks “Interior Angles Of Polygons”: (finding patterns) • Worksheet (page 10) 10 marks “Challenge Yourself”: (using what we have learned) • Triangle (page 10) 10 marks • Quadrilateral (page 10) 10 marks “This Is How I Did”: (self evaluation) (page 11) • Question #1 5 marks • Question #2 5 marks • Question #3 20 marks TOTAL: 100 MARKS Page 2 WORD WEB TRIANGLES Page 3 WORD WEB QUADRILATERAL Page 4 What a rip-off 1. DRAW A TRIANGLE (try to use up a large portion of the grid paper) 2. LABEL THE THREE ANGLES (example a, b, c) 3. NAME YOUR TRIANGLE (example abc) 4. MEASURE EACH OF THE THREE ANGLES AND WRITE THE MEASURE ON EACH ANGLE (example a = 37º) 5. CUT OUT YOUR TRIANGLE 6. RIP OFF THE THREE ANGLES OF YOUR TRIANGLE 7. GLUE YOUR ANGLES ON TO THE “ANGLES CAN BE A REAL RIP OFF” PAGE. Page 5 What a rip-off 1. DRAW A QUADRILTERAL (try to use up a large portion of the grid paper) 2. LABEL THE FOUR ANGLES (example a, b, c, d) 3. NAME YOUR QUADRILATERAL (example abcd) 4. MEASURE EACH OF THE FOUR ANGLES AND WRITE THE MEASURE ON EACH ANGLE (example a = 37º) 5. CUT OUT YOUR QUADRILATERAL 6. RIP OFF THE FOUR ANGLES OF YOUR TRIANGLE 7. GLUE YOUR ANGLES ON TO THE “ANGLES CAN BE A REAL RIP OFF” PAGE. Page 6 ANGLES CAN BE A REAL RIP-OFF The sum of the three angles you measured is a=___ b=___ c =___ a+ b+ c= The sum of your three ripped off triangle angles is____________ How close were you?________________ Place your three vertices here. Place your four vertices here. The sum of the four angles you measured is a = ___ b = ___ c = ___ d = ___ a+ b+ c+ d= The sum of my ripped off quadrilateral angles is ________ How close were you?____________ Page 7 WORD WEB PENTAGON Page 8 INTERIOR ANGLES OF POLYGONS NUMBER OF NUMBER OF NUMBER OF SHAPE DIAGRAM TOTAL NUMBER OF SIDES ANGLES TRIANGLES DEGREES BECAUSE... We discovered that the sum of the three angles of a TRIANGLE triangle is always 180° 3 3 1 A quadrilateral is made up of two triangles. So if a QUADRILATERAL 1 triangle is 180° then the sum of the four angles of a 2 4 4 2 quadrilateral must equal 2 x 180° = 360° PENTAGON 1 2 3 HEXAGON HEPTAGON OCTAGON DECAGON DODECAGON CHALLENGE!! A 44 SIDED POLYGON IS CALLED A TETRACONTAKAITETRAGON. CAN YOU CALCULATE WHAT THE SUM OF ITS INTERIOR ANGLES WILL BE?????? (Of course you can!!) Page 9 CHALLENGE YOURSELF! Draw the following triangle. ghi Where g=50° h=70° i= ? ° Draw the following quadrilateral. bcde Where b= 90° c= 75° d= ? ° Page 10 e= 100° THIS IS HOW I DID ABOUT ANGLES? NAME:____________________________________ 1 Write about at least 5 things that you learned this week. 2 What I found difficult was….. 3. Place a star on the following scales, giving yourself a mark out of 5 for each category. • I WAS A HELPFUL COOPERATIVE PARTNER 1 2 3 4 5 • MY WORK IS NEAT, CLEAR AND ORGANIZED 1 2 3 4 5 • MY DIAGRAMS ARE NEAT AND CLEAR 1 2 3 4 5 • MY COMPLETED WORK SHOWS A CLEAR UNDERSTANDING OF ANGLES AND POLYGONS 1 2 3 4 5 Page 11
