We have an isosceles $\triangle ABC, AC=BC, \measuredangle ACB=40^\circ$ and a point $M$ such that $\measuredangle MAB=30^\circ$, $\measuredangle MBA=50^\circ$.
Find $\measuredangle BMC$.
Starting with $\angle ABC=\angle BAC=70^\circ \Rightarrow \angle CBM=20 ^\circ$. Let us construct the equilateral $\triangle ABH$. I... | 677.169 | 1 |

Prove and use theorems involving lines that intersect a circle at two points.
Segments from Secants
When two secants intersect outside a circle, the circle divides the secants into segments that are proportional with each other.

Ok i figured it out. For anyone curious, draw an equilateral triangle in triangle ACD by drawing a parallel line to AB. Label the point E so you have an equilateral triangle ADE. Notice triangle CDE and ABC are similar. And see what you can do from there :)
If we draw a parallel line to $A... | 677.169 | 1 |

Properties of Circle
Lines and circles are the important elementary figures in geometry. We know that a line is a locus of a point moving in a constant direction, whereas the circle is a locus of a point moving at a constant distance from some fixed point. The theoretical importance of the circle is reflected in the n... | 677.169 | 1 |
