Right Isosceles Triangle

Written by Jerry Ratzlaff on . Posted in Plane Geometry

  • One side of a right isosceles triangle is 90° and the other two angles are equal.right isosceles triangle
  • 3 edges
  • 3 vertexs

Edge formula

\(a = P - b - c   \)

\(a = 2 \frac {A} {b\;\sin y} \)

\(b = P - a - c   \)

\(b = 2 \frac {A}{h} \)

\(c = P - a - b   \)

Where:

\(a\) = edge

\(b\) = edge

\(c\) = edge

\(P\) = perimeter

\(A\) = area

Height formula

\(h = 2 \frac {A}{b} \)

Where:

\(h\) = height

\(b\) = edge

\(A\) = area

Perimeter formula

\(P = a + b + c \)

Where:

\(P\) = perimeter

\(a\) = edge

\(b\) = edge

\(c\) = edge

Area formula

\(A= \frac {hb} {2} \)

\(A = ab \frac {\sin y} {2} \)

Where:

\(A\) = area

\(b\) = edge
