A Wedge is a polyhedral solid defined by two triangular faces and three trapezoidal faces. It looks like a doorstop, a tent, or a slice of cheese. In geometry, it is technically known as a general prismatoid. This shape is unique because the top edge ($c$) can be a different length than the base edge…
A Major Sector is what remains of a pizza after you take a slice out. Mathematically, it is a sector with a central angle greater than $180^\circ$. While most textbooks focus on the “Minor Sector” (the slice), real-world applications often require measuring the “Major Sector” (the rest of the pie), such as in land surveying…
A Major Segment is the larger portion of a circle when it is cut by a chord. While the “Minor Segment” is the small crust, the Major Segment is the rest of the pie—always covering more than 50% of the circle’s area. This calculator is designed to solve for this larger area specifically, which…
Minor Sector Calculator A Sector is what most people call a “slice of pizza.” It is the region bounded by two radii and an arc. A “Minor Sector” specifically refers to a slice smaller than a semicircle (Angle < 180°). Calculating this area is one of the most common tasks in geometry, used everywhere…
An Isosceles Triangle is a triangle that has at least two sides of equal length. Consequently, the angles opposite these equal sides (Base Angles) are also equal. This symmetry makes it one of the most structurally stable shapes, widely used in architecture (A-frame houses), bridge trusses, and graphic design. Calculator Features 1. Four Calculation Modes…
Scalene Triangle Calculator A Scalene Triangle is the most common type of triangle found in nature and random geometry. Unlike isosceles or equilateral triangles, a scalene triangle has no equal sides and no equal angles. Because it lacks symmetry, calculating its area often requires more advanced methods like Heron’s Formula or Trigonometry. Calculator Features…
Calculator Wrapper An Obtuse Triangle is a triangle that has one angle greater than $90^\circ$ (an obtuse angle). Because the internal angles of any triangle add up to $180^\circ$, the other two angles must be acute (less than $90^\circ$). Visually, it looks “reclined” or “leaning back.” Calculating its area can be tricky because the…
Calculator Wrapper An Acute Triangle is a triangle where all three internal angles are less than 90°. Unlike right triangles (one 90° angle) or obtuse triangles (one angle > 90°), an acute triangle is “sharp” at every corner. This implies that the “height” falls inside the triangle regardless of which side you treat as…
Calculator Wrapper A Non-Right Triangle (or Oblique Triangle) is any triangle that does not have a $90^\circ$ angle. It can be either acute (all angles < 90°) or obtuse (one angle > 90°). Standard trigonometry shortcuts like $a^2 + b^2 = c^2$ (Pythagoras) DO NOT work here. You must use the Laws of Sines…
Calculator Wrapper The Triangle Area Using Vectors Calculator is a specialist tool that skips the geometry of “sides” and “angles” and works directly with the pure math of Magnitude and Direction. It is designed for physics students and engineers who define shapes not by where they are (points) but by how they span space…
