View Angles Of A Five Pointed Star
Background. B is also part of the isosceles triangle, so to find angle c at the top 72⁰ + 72⁰ = 144⁰. Restrictions (to make clear that this is neither a maths problem as opposed to a maths puzzle nor an exercise in computation or advanced this is an image of an arrow sweeping each of the successive angles in the star.
Simple star. 4, 5, 6 and 7 pointed version with two ... from c8.alamy.com
From the figure shown, angles adc, aob, and boc are equal; Five angles in a star. Looking at any of the five.
It's important to leave enough space around.
Can you prove that the angles in all five points still sum to 180 degrees? What is the value of each angle of a regular dodecagon? Here's a cute little exercise for students taking a beginning geometry class: Join points a and c, crease, and unfold.
