Similarity and Congruence Two objects are similar if they have the same shape, so that one is an enlargement of the other. Two objects are congruent if they are the same shape and size. Corresponding angles are equal. Corresponding lengths are in the same ratio – they have the same Scale Fac... | 677.169 | 1 |
To construct a triangle similar to a given ∆ABC with its sides 3/7 of the corresponding sides of ∆ABC, first draw a ray BX such that∠CBX is an acute angle and X lies on the opposite side of A with respect to BC. Then, locate points B1,B2,B3,.......... on BX at equal distances and next step is to join | 677.169 | 1 |
Proposition 48, which is the converse of the famous Pythagorean theorem (Prop 47) is the topmost theorem in Book I - in blue to the right.
If in a triangle the square on one of the sides equals the sum of the squares on the remaining two sides of the triangle, then the angle contained by the remaining two sides of the... | 677.169 | 1 |

Line Segment Bisector
Definition: A line, ray or segment which cuts another line segment into two equal parts.
Try this Drag one of the orange dots at A or B and note the the line AB always
divides the line PQ into two equal parts.
In general 'to bisect' something means to cut it into two equal parts. The 'bisector'... | 677.169 | 1 |
Angle of parallelism In hyperbolic geometry, the angle of parallelism \Pi(a) , is the angle at one vertex of a right hyperbolic triangle that has two asymptotic parallel sides. The angle depends on the segment length ''a'' between the right angle and the vertex of the angle of parallelism. Given a point off of a line, ... | 677.169 | 1 |
An Overview
The theorem on the exterior angle of a cyclic quadrilateral is used to state the property of cyclic quadrilaterals and helps us in solving complex problems related to exterior angles in an easy and efficient manner. Cyclic quadrilaterals are the quadrilaterals that are formed when all the vertices of the q... | 677.169 | 1 |
