Explanation:

g, h — properties of isosceles triangles

a — supplementary to a given angle

e — corresponding to angle a

c — same side interior with angle b

d — supplementary to a given angle and angle e

r — supplementary to angle p

s — corresponding to angle p

k — supplementary to angle h

f, m, p — triangle sum theorem

e — vertical to angle c

b — vertical to a given angle

Properties of isosceles triangles→g,h

Supplementary to a given angle→a

Corresponding to angle a→e

Same side interior with angle b→c

Supplementary to a given angle and angle e→d

Supplementary to angle p→r

Corresponding to angle p→s

Supplementary to angle h→k

Triangle sum theorem→f,m,p

Vertical to angle c→e

Vertical to a given angle→b
