NettetAn equilateral triangle has three lines of symmetry. It has rotational symmetry of order 3. It has three equal sides. All three angles are equal (60°) Right-angled triangle A... NettetWe can use the following equation to represent the triangle: x^\circ + 42^\circ + 106^\circ = 180^\circ x∘ + 42∘ + 106∘ = 180∘ The missing angle is 180^\circ 180∘ minus the measures of the other two angles: x^\circ = … how often is afib misdiagnosed

NettetThis activty gets the pupils to see the relationship between rotational symmetry and angles. It should also become clear that every shape has at least order one rotational symmetry (important terminology that needs to be introduced) since an angle of 0 degrees can be used. Demonstrating from the front can be effective, but the real power … NettetWhat is the order of rotational symmetry for a rhombus? 2. How many lines of reflectional symmetry does an equilateral triangle have? 3. If the smallest angle of rotation for a regular polygon is 18°, how many sides does polygon have? 20. Which set of side lengths represents a triangle with 3 lines of reflectional symmetry? 5, 5, 5. NettetA shape with 4 equal sides and no right angles.
