Answer 1

You need two equal sides and one angle > 90° (the apex) to make an isosceles obtuse triangle. A simple way to do that in your drag interface:

1. Make K and L the base points. Drag K left and L right so the base KL is horizontal and about 6 units long (for example).
2. Move M to the perpendicular bisector of KL (i.e., directly above or below the midpoint of KL) so KM = LM. Watch the side-length readouts and stop when KM and LM match (or are very close).
3. To make the apex angle obtuse, keep M fairly close to the base (inside half the base length). For a concrete target: place K ≈ (−3, 0), L ≈ (3, 0) and M ≈ (0, 2). That gives:
- base KL ≈ 6
- equal legs KM = LM ≈ 3.61
- apex angle at M ≈ 112.6° (obtuse)

So, in the app: drag K and L to make a horizontal base about 6 units long, then drag M to the midpoint above (or below) the base and closer than 3 units to the base line until the two side lengths match and the angle at that vertex is >90°.
