 A', ZB = Z B', ZC = Z C". The first two statements cannot be true, for the sum of the angles of the two triangles would exceed four right angles. Therefore, two angles of one triangle are equal to two angles of the other.  Mathematics - Page 193by United States. Bureau of Naval Personnel - 1951Full view - About this book

...ways to identify similar triangles. Here they are: 1. AA (angle, angle): by identifying that at least two angles of one triangle are equal to two angles of the other triangle. Note: If two sets of angles are congruent, the third angle is also congruent. 2. SAS (side, angle,... | |

...angles of the other. (AAA similarity). As the sum of the angles of a triangle is 180°, it is enough if two angles of one triangle are equal to two angles of the other, for the two triangles to be similar [AA corollary] 11. If the sides of one triangle are proportional... | |

...Proof : In A ABD and A ACD : ZB = ZC [Given] Z ADB = Z ADC [AD 1 BC] = 90° => Z BAD = Z CAD [When two angles of one triangle are equal to two angles of the other trianglejtheir third angles are also equal] Also, AD = AD [Common side] A ABD = A ACD [By ASA] => AB... | |

...enter into the function Ф, and we have simply с = ф: (A, [;).' This formula already proves, that if two angles of one triangle are equal to two angles of another, the third angle of the former must also be equal to the third of the latter ; and this granted,... | |
