BC = 6 cm. These numbers are Pythagorean triples, the triangles are right angled, the inscribed circle of the first has radius 1 unit and the second has radius 2 units. The same is true for ′ . AB = 8 cm. Therefore two of its sides are perpendicular. Approach: Formula for calcula... | 677.169 | 1 |
Trigonometry
2. The word trigonometry is derived from the Greek
words: (i) trigonon and (ii) metron. The word
trigonon means a triangle and the word metron
means a measure.
Hence, trigonometry means the science of
measuring triangles. In broader sense it is that
branch of mathematics which deals with the
measureme... | 677.169 | 1 |

Square
When constructing square ABED I started with circle A, and copied it three times to create circles B, E, and D. Circle A had the radius B and D, circle B had radius E and A, circle E had radius B and D, and circle D had radius A and E. Then, I created sides AB, BE, ED, and DA which are congruent because they're... | 677.169 | 1 |

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are on the plane where the rays are located. The meeting of two planes also creates angles. Dihedral angles are these.
A pair of ra... | 677.169 | 1 |
