## Improve your math skills with this free online course covering ratios, angles, geometric reasoning, and more.

Geometry
Free Course
Geometry and Trigonometry is one of the strands of the new Project Maths Course in the Irish curriculum. Synthetic Geometry and Co-ordinate Geometry help us understand the dimensions and transformations of shapes and figures including lines, triangles, polygons, and circles. This course teaches how to find sides and angles using different ratios. You will learn about geometric reasoning, equations of a straight line, and more.

## Description

A ratio is a relationship between two numbers. It tells how much of one thing there is compared to another thing. This course begins by teaching the steps in finding angles and sides using trigonometrical ratios such as sine, cosine, and tangent ratios. You will then learn about different applications of geometric reasoning, which is the use of critical thinking, logical arguments, and spatial reasoning to solve problems and find new relationships.

Coordinates are a set of values that show an exact position, and are usually a pair of numbers you can see on graphs. This course will teach you about geometry with coordinates. You will look into the equation of a straight line, parallel lines, and perpendicular lines. You will also study the Pythagorean theorem which is a mathematical formula that provides us with the relationship between the sides in a right-angled triangle.

Trigonometry is used to measure angles while geometry deals with angles only in terms of equality of angles and sums of angles. Upon the completion of this course, you will have a better understanding of synthetic geometry, right-angled triangles, coordinate geometry, and trigonometrical ratios. You will also be able to practice answering miscellaneous trigonometry questions. So, check out the course today and starting give your maths skills a solid boost.
