How to work with Angles: Part 1

Angles are all around us. We even have a musical instrument called the triangle! But before you start revising all the angle facts – why not check out some fun facts about some other musical instruments.

Musical instruments come in all shapes, styles and sizes, made out of many different materials. And there are thousands of different ones to choose from. Many thousands of years ago, people made sounds from natural objects like shells, and parts of plants. However, historians cannot agree on how old the first object which can be described as a musical instrument actually is. Many believe that the oldest instrument is a “Neanderthal Flute” – from as far back as 67,000 years.  Others refer to a flute found around 37,000 years ago.  Chinese archaeologists discovered the first playable instrument, and it is around 9000 years old. Fashioned from the hollow bone of a very large bird, it has 7 holes in it. Our ancestors used wood, bones and animal skins to make instruments. As these will long since have broken down- it is impossible to tell how long ago this started.

There are some very strange looking and sounding instruments around. The Hornocupian Dronepope is one of the first ever instruments produced from 3D-printing.  It was designed for an art installation, although it can actually be played. Unbelievably someone made an instrument called a Badgermin. This is an electronic musical instrument, controlled by the musician without any physical contact, called a theremin placed inside a badger! If this is not weird enough for you, a man in the Netherlands made a working drum set entirely out of cheese.

Check out this week’s guide: How to work with Angles Part 1. This guide describes the different types of angle and covers some key angles facts. Included in the guide is information on angles in triangles, straight lines, around a point and in quadrilaterals.  It also explains how to use these angle facts to answer questions.  You can check your understanding by trying the questions and answers inside.
