# Summer of Shapes Part 1

Jul 16, 2021 | Kerrisdale

During the summer we're challenging our students (and anyone else who is interested) to go on a Shape Scavenger Hunt! Keep an eye out for any interesting geometric shapes, objects, and angles you pass everyday! Here are some that we spotted around our center and the general Kerrisdale Area.

First, here's an isosceles triangle spotted "in the wild" (or just in front of our center). Isosceles triangles can be identified by their two sides that are the same length! Can you spot the second hidden isosceles triangle in this picture?

Next, we found a moment with some interesting angles! Here's an Acute Angle between the minute and hour hands (about 78°), and an Obtuse Angle between the second and hour hands (about 150°). Also in this picture is a reflux angle (greater than 180°, less than 360°), can you find it?

Here's a trapezoid we spotted across the street from our center! There's some debate about what makes a trapezoid; we all know it has four straight sides but some definitions say trapezoids have ONLY one pair of parallel sides, while others say they need AT LEAST one pair of parallel sides. If we take the second definition (at least one pair of parallel sides), this picture is full of trapezoids! How many can you find?

Similar to the isoceles triangle, is a scalene triangle! What sets scalene triangles apart is none of their three sides or angles are the same size. We use one, two, and three lines, each through a different side to illustrate this. "Scalene" is how we classify the sides of a triangle, but scalene triangles can be acute, right, or obtuse!

Moving away from two dimensional shapes, we have a cylinder! As a 3D Object rather than a 2D Shape, what you see depends on the angle you're viewing it from. On the left, looking at it straight on you see a rectangle, while on the right, looking at the same object from above you see a circle. Put these two views together and you get a cylinder!

That's all for this update, but we will keep searching for exciting shapes, angles, and objects in the wild, and encourage you all to do the same!
