Euclid Book I PROP. XXI. -- THEOREM.

Saturday, Jun 13, 2020

If two lines (BD, CD) be drawn to a point (D) within a triangle from the extremities of its base (BD), their sum is less than the sum of the remaining sides (BA, CA), but they contain a greater angle.

Euclid Book I PROP. XX. -- THEOREM.

Friday, Jun 12, 2020

The sum of any two sides (BA, AC) of a triangle (ABC) is greater than the third.

Euclid Book I PROP. XIX. -- THEOREM.

Thursday, Jun 11, 2020

If one angle (B) of a triangle (ABC) be greater than another angle (C), the side (AC) which it opposite to the greater angle is greater than the side (AB) which is opposite to the less.

Euclid Book I PROP. XVIII. -- THEOREM.

Wednesday, Jun 10, 2020

If in any triangle (ABC) one side (AC) be greater than another (AB), the angle opposite to the greater side is greater than the angle opposite to the less.

Euclid Book I PROP. XVII. -- THEOREM.

Tuesday, Jun 9, 2020

Any two angles (B, C) of a triangle (ABC) are together less than two right angles.

Euclid Book I PROP. XVI. -- THEOREM.

Monday, Jun 8, 2020

If any side (BC) of a triangle (ABC) be produced, the exterior angle (ACD) is greater than either of the interior non-adjacent angles.

Euclid Book I PROP. XV. -- THEOREM.

Sunday, Jun 7, 2020

If Two right lines (AB, CD) intersect one another, the opposite angles are equal (CEA=DEB, and BEC=AED)

Euclid Book I PROP. XIV. -- THEOREM.

Saturday, Jun 6, 2020

If at a point (B) in a right line (BA) two other right lines (CB, BD) on opposite sides make the adjacent angles (CBA, ABD) together equal to two right angles, these two right lines form one continuous line.

Euclid Book I PROP. XIII. -- THEOREM.

Friday, Jun 5, 2020

The adjacent angles (ABC, ABD) which one right lines (AB) standing on another (CD) makes with it are either both right angles, or their sum is equal to two right angles.

Euclid Book I PROP. XII. -- PROBLEM.

Thursday, Jun 4, 2020
