G7  Circle theorems (angles)
This video demonstrates all the angle based circle theorems you need for GCSE maths. Then in the links below there will be lots of practice questions
for you to check you can do them in varing situations.

G8  Circle theorems (lengths)
This video from maths247 explains the intersecting chord theorm for both versions, where they cross inside the circle and when they cross outside the circle.

G9  Proof of congruence of two triangles
Maths247 goes through the different cases that prove triangles of congruence followed by a couple of examples of exam questions. This is not a common topic
and It has not been on any of the exam papers so far, but this doesnt mean it wont be on the next one.

G12  Vector geometry
This video is the first in a play list that includes practice questions. It is a bit old school as early maths247 videos are videos of him writing on paper
but as always quality teaching.

G13  Similar shapes length, area and volume
In this video Hegarty explains what we mean by the word similar in mathematics, it also goes through how to change from a length to area to volume
scale factor and does a few nice examples. Check out the Maths247 video which is very similar (no pun intended)

G15a  Trigonometric ratios in rightangled triangles
This video recaps the method used to find the missing angle in a right angled triangle when you are given two side lengths. There is an example for each
of the three trig ratios sin, cos and tan. It also works through three examples of finding lengths when given an angle and a side on for each of sin, cos and tan.

G18  Area and Perimeter of sectors of circles
This video starts with some basic circle info but works through sectors from the point at which I linked it, this topic can be really tricky
try the Maths2472 for something difficult.

G19Calculate the area of triangle using 1/2abSinC
This video starts with some basics on triangles but I have linked from the section on the formula for any triangle where you have an angle
and the two sides either side of it. Like most exam questions using this rule it comes after a cosine rule part in the following.
