Mr rouche's maths: hi everyone! just a little background about me: i'm a maths teacher currently teaching in australia but i've taught from year 7 to 12 in the uk and south africa. i had a couple of my students ask me to give them my board notes that i use to teach from but since i've moved schools some of my notes have been taken off line and.

If it is a regular polygon (all sides are equal, all angles are equal) shape sides sum of interior angles shape each angle; triangle: 3: 180° 60° quadrilateral: 4: 360° 90° pentagon: 5: 540° 108° hexagon: 6: 720° 120° heptagon (or septagon) 7: 900° 128.57 ° octagon: 8: 1080° 135° nonagon: 9: 1260° 140° any polygon: n (n−2. We can learn a lot about regular polygons by breaking them into triangles like this: notice that: the "base" of the triangle is one side of the polygon. the "height" of the triangle is the "apothem" of the polygon. now, the area of a triangle is half of the base times height, so: area of one triangle = base × height 2 = side × apothem 2. Explain you answer. this activity makes an ideal homework for students to investigate the concept of interior and exterior angles. a discussion at the beginning of the next lesson (for example on the question about any 12 sided shape) will then reinforce the learning from the investigation. alternatively, you could do this investigation in a.

Exterior angles sum to 360 degrees: for any polygon, the sum of the exterior angles, one at each vertex, is always 360 degrees. this is true regardless of the number of sides. when a problem involves exterior angles, remember that dividing 360 degrees by the number of sides will give you the measure of each exterior angle in a regular polygon.
