Circle Theorems Part 2 | Geometry & Measures | Maths | FuseSchool
Let’s discover some more circle theorems so that we can solve all types of geometrical puzzles.
We discovered these 4 theorems in part 1:
Angle at the centre is double the angle at the circumference
The angle in a semi-circle is 90 degrees
Angles in the same segment are equal / Angles subtended by the same arc are equal
Opposite angles in a cyclic quadrilateral add up to 180 degrees.

Watch part 3 to discover the final 2 theorems that involve intersecting chords.

In this video you'll learn the basics about Ionic Bonds.

In this video, we are going to look at parallel lines. To find the equation of parallel lines, we still use the y=mx + c equation, and because they have the same gradient, we know straight away that the gradient ‘m’ will be the same. We then just need to find the missing y-intercept ‘c’ value.

Plants have developed responses called tropisms. A tropism is a growth in response to a stimulus; so light and water in the plant’s case.
There are different types of tropisms: Positive tropisms are when growth is towards the stimulus - so the plant growing towards the light to maximise the stimul
