What reading level is Plane Geometry book?
To quickly assess the difficulty of the text, read a short excerpt:
Prove it. 9. If two circles are tangent externally, the corresponding segments of two lines drawn through the point of contact and terminated by the circles are proportional. 10. If two circles are tangent externally, their common ex- ternal tangent is the mean proportional between their diameters. 11. AB and AC are chords drawn from any point A on a circle, and AD is sl diameter. If the tangent at D intersects AB and AC 2it E and F, the triangles ABC and AEFave similar. 12. If ^D and BE are tw...o altitudes of the triangle ABC, the triangles DEC and ABC are similar. P^'" 172 BOOK III. PLANE GEOMETEY Proposition XVIII. Theorem 292. If tivo polygons are similar^ they can he sepa- rated into the same number of triangles^ similar each to each^ and similarly placed. Given two similar polygons ABCDEand, A^B^CD'E' with angles Ay B, C, 2), E equal to angles A\ B\ C\ D\ E^ respectively.
