The best name of a quadrilateral whose diagonals bisect each other at right angles (perpendicular bisectors) is a rhombus.
A rhombus is a quadrilateral with parallel opposite sides whose diagonals bisect each other at right angles. A square is a special type of rhombus with the additional property that the i... | 677.169 | 1 |
"Draw a triangle"
Ask a friend to draw a triangle — the one that comes immediately to their mind's eye on hearing the word "triangle". This is an experiment proposed by Eleanor Robson in her article Words and Pictures. What are the results? Do we differ from the ancient Mesopotamian scribe … or from each other?

The ellipse's shape is controlled a) through segment AB (equal to A*B*), defining length (d), and b) through the polar angle (alpha). Switch to the selection-tool ( CTRL+1 ) to modify AB. Switch to the selection-on-contour tool ( CTRL+2 ) to modify (alpha), by moving G on the circle. The blue ellipse is a 45-degrees ro... | 677.169 | 1 |
Definition of congruent angle
What is meant by congruent angles?
Congruent angles are two or more angles that are identical to each other. Thus, the measure of these angles is equal to each other. The type of angles does not make any difference in the congruence of angles, which means they can be acute, obtuse, exter... | 677.169 | 1 |
Concave Polygons vs. Convex Polygons: What's the Difference?
Concave polygons have at least one interior angle greater than 180° and inward indentations; convex polygons have all interior angles less than 180°, forming a bulged shape.
Key Differences
Concave polygons exhibit at least one interior angle exceeding 180... | 677.169 | 1 |

Introducing angle measures (and using arcs) without taking seriously the quantification of angle measure likely sends students the message: use these numbers to perform calculations and find other numbers, but do not worry about what the numbers, arcs, and calculations mean. (p. 244)

Reversed Reversed Curve as PDF for free.
More details
1. A reversed curve is to connect two tangents which are parallel to each other and are 200m apart with directions due east . There is an intermediate tangent of 200m between the reversed curve and the horizontal distance of the P.C. and P.T. measured parallel to ... | 677.169 | 1 |
If three semicircles R, S and Ttouch at A, B and C,
Then there exists an infinite family of circles {C1,C2,...} such that
C1 touches R, S and T,
for n > 1, Cn touches R, S and Cn-1
This result is called the arbelos since the shape bounded by the semicircles resembles that of an

GIVEN: ∆ABC is a right triangle. So, either ∠w or ∠v is 90° However, if ∠w = 90° then ∆ABC CANNOT be a right triangle. Why not? Well, if ∠w = 90°, then ∠ABD must be GREATER THAN 90°, and since the 3 angles in ∆ABC must add to 180°, the other two angles (∠BAC and ∠BDC) must be less than 90°
So, we can be certain that ∠... | 677.169 | 1 |
In a circle, if we pick any two distinct points $p_1$ and $p_2$ and draw a line passing through $p_1$ and $p_2$ that line is parallel to the line tangent to the circle at the midpoint of the arc with endpoints $p_1$ and $p_2$.
Are there curves other than cicles such that is true? What about parabolas?
