The Sulba Sutras are a collection of ancient Indian mathematical texts that contain geometric constructions and rules for constructing altars. They are believed to have been written between 800 and 500 BCE.

The Pythagorean theorem is a geometric construction that states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. It is one of the most famous and widely used theorems in geometry.

A rhombus is a geometric figure that is formed by connecting the midpoints of the sides of a rectangle. It is a parallelogram with four equal sides.

The golden ratio is a geometric construction that divides a line segment into two parts so that the ratio of the longer part to the shorter part is the same as the ratio of the whole line segment to the longer part. It is often found in nature and art.

Aryabhata was an Indian mathematician who is credited with discovering the concept of zero. He also developed a system of positional notation that is still used today.

Pascal's triangle is a geometric construction that is formed by arranging numbers in a triangular pattern. It is named after the French mathematician Blaise Pascal, who studied it in the 17th century. However, it was first described by Bhaskara II in the 12th century.

Brahmagupta was an Indian mathematician who is credited with developing the concept of the sine function. He also developed a formula for calculating the area of a triangle.

Euler's formula is a mathematical formula that relates the exponential function to the trigonometric functions. It is named after the Swiss mathematician Leonhard Euler, who discovered it in the 18th century. However, it was first described by Varahamihira in the 6th century.

Bhaskara II was an Indian mathematician who is credited with developing the concept of the cosine function. He also developed a formula for calculating the area of a circle.

Aryabhata was an Indian mathematician who is credited with discovering the concept of zero. He also developed a system of positional notation that is still used today. Additionally, he described the Pythagorean theorem in his work, the Aryabhatiya.

Brahmagupta was an Indian mathematician who is credited with developing the concept of the tangent function. He also developed a formula for calculating the area of a triangle.

Varahamihira was an Indian mathematician and astronomer who is credited with developing the concept of the golden ratio. He also wrote a number of works on astronomy and astrology.

Bhaskara II was an Indian mathematician who is credited with developing the concept of the secant function. He also developed a formula for calculating the area of a circle.
