Tell wether the statement is always, so
Etimes, or never true. Justify your reasoning and i clude example .The sum of any two angle measures in an acute triangle is greater than 90 degree.

  • Classifyng triangles -

    since no angle is greater than 90 degrees, if the angles are A,B,C, then since C<90, and A+B+C = 180

    A+B > 90

    always true.
