As shown in the figure, △ ABC, D is the midpoint of AB, e is the point above AC, be ‖ DF, BD ‖ EF, DF intersects AC with G. verification: Ag = eg


If the quadrilateral befd is a parallelogram, then EF is parallel to BD
And ad = BD, so EF is parallel to AD. if de and AF are connected, the quadrilateral ADEF is a parallelogram
So Ag = eg

On a mathematical problem of solving triangles in the second year of senior high school,
It is known that in △ ABC, a, B and C are opposite sides of a, B and C respectively. It is known that two radical signs 2 (Sin & sup2; a-SiN & sup2; c) = (a-b) SINB, and the radius of circumscribed circle of △ ABC is radical sign 2
1 find angle c
2 find the maximum area s of △ ABC


Note that a / 2R = Sina,
That is, sine theorem a / Sina = B / SINB = C / sinc = 2R, both sides of the above formula multiply by 2R
There is a ^ 2-C ^ 2 = (a-b) B, that is, a ^ 2 + B ^ 2-C ^ 2 = ab
From the cosine theorem
CosC=(a^2+b^2-c^2)/2ab=1/2
So C = 60 degrees
The largest area can be drawn, because C = 60 ° C = 2R * sinc = root 6
First, draw the circumscribed circle. The length of AB is fixed. Let's see when the height is the highest. Just when ABC is an isosceles triangle, the height is the highest. It's easy to see from the figure. At this time, it's an equilateral triangle and the area is easy to find. It's 3 * root 3 / 2
